refactor(webkit): migrate core package to gotk4, update workspace types

Replace manual CGO webkit bindings with clean gotk4-based implementation.
This is phase 1 of the migration - core types and structure complete.

Package Changes:
- Deleted 40 CGO files (~5000 lines of manual bindings)
- Created 6 new files (~500 lines clean Go code)
  - mainloop.go: GTK main loop management
  - types.go: Config, WindowType, WindowFeatures
  - widgets.go: Paned, Box, Label, Image wrappers
  - webview.go: WebView wrapper with event handlers
  - window.go: Window wrapper
  - errors.go: Error definitions

Type System Updates:
- paneNode.container: uintptr → gtk.Widgetter
- paneNode.titleBar: uintptr → gtk.Widgetter
- paneNode.stackWrapper: uintptr → gtk.Widgetter
- paneNode.orientation: webkit.Orientation → gtk.Orientation

Workspace Updates:
- initializePaneWidgets() now accepts gtk.Widgetter
- setContainer/setTitleBar/setStackWrapper use gtk.Widgetter
- mapDirection() returns gtk.Orientation

Dependencies:
- Added gotk4/pkg v0.3.1
- Added gotk4-webkitgtk/pkg v0.0.0-20240108031600-dee1973cf440

Next Steps:
- Update stacked_panes.go widget operations (~100 locations)
- Update workspace_pane_ops.go split operations (~50 locations)
- Fix remaining compilation errors in ~23 browser files

	2	+
	3	+	## YES, You Can Regenerate gotk4-webkitgtk Bindings!
	4	+
	5	+	### Current State
	6	+	- gotk4-webkitgtk: Last updated Jan 8, 2024 (~1 year old)
	7	+	- gotk4: Actively maintained (last update Jul 3, 2025)
	8	+	- Status: ✅ WORKS WITH LATEST GOTK4 (confirmed by recent test)
	9	+	- WebKitGTK 6.0: ✅ SUPPORTED (import path: `webkit/v6`)
	10	+
	11	+	### Good News from Research
	12	+	The last comment on the compatibility issue (recent) confirms:
	13	+	```go
	14	+	import webkit "github.com/diamondburned/gotk4-webkitgtk/pkg/webkit/v6"
	15	+	// Works perfectly with gotk4 v0.3.2!
	16	+	```
	17	+
	18	+	---
	19	+
	20	+	## Option 1: Use Existing gotk4-webkitgtk (RECOMMENDED)
	21	+
	22	+	### Why This Works
	23	+	- Bindings were regenerated Jan 2024 with GTK4 WebKitGTK
	24	+	- Compatible with latest gotk4 (v0.3.2+)
	25	+	- Already supports webkitgtk-6.0
	26	+	- No need to regenerate unless you need bleeding-edge APIs
	27	+
	28	+	### Migration Steps
	29	+	```bash
	30	+	# Add dependencies
	31	+	go get github.com/diamondburned/gotk4/pkg@latest
	32	+	go get github.com/diamondburned/gotk4-webkitgtk/pkg@latest
	33	+
	34	+	# Imports will be:
	35	+	import (
	36	+	"github.com/diamondburned/gotk4/pkg/gtk/v4"
	37	+	"github.com/diamondburned/gotk4/pkg/gdk/v4"
	38	+	webkit "github.com/diamondburned/gotk4-webkitgtk/pkg/webkit/v6"
	39	+	)
	40	+	```
	41	+
	42	+	---
	43	+
	44	+	## Option 2: Regenerate Bindings for Latest WebKitGTK
	45	+
	46	+	### When to Regenerate
	47	+	- Need WebKitGTK APIs added after Jan 2024
	48	+	- Want to contribute upstream improvements
	49	+	- Customize bindings for your specific needs
	50	+
	51	+	### How to Regenerate (3 Methods)
	52	+
	53	+	#### Method A: Using Nix (Recommended by gotk4 maintainer)
	54	+
	55	+	```bash
	56	+	# 1. Install Nix (if not already)
	57	+	curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix \| sh -s -- install
	58	+
	59	+	# 2. Clone gotk4-webkitgtk
	60	+	git clone https://github.com/diamondburned/gotk4-webkitgtk.git
	61	+	cd gotk4-webkitgtk
	62	+
	63	+	# 3. Update shell.nix to use webkitgtk_6_0 (already configured!)
	64	+	# See: buildInputs includes webkitgtk_6_0
	65	+
	66	+	# 4. Enter Nix environment
	67	+	nix-shell
	68	+
	69	+	# 5. Regenerate bindings
	70	+	go generate
	71	+
	72	+	# Bindings will be regenerated with your system's WebKitGTK version!
	73	+	```
	74	+
	75	+	#### Method B: Fork abergmeier's Updated Generator
	76	+
	77	+	A community member already fixed the generator:
	78	+	```bash
	79	+	# Clone the updated fork
	80	+	git clone https://github.com/abergmeier/gotk4-webkitgtk.git -b webkitv6
	81	+	cd gotk4-webkitgtk
	82	+
	83	+	# This fork uses gotk4-adwaita's newer genmain package
	84	+	# Should work with latest WebKitGTK 6.0
	85	+	```
	86	+
	87	+	#### Method C: Update Generator Yourself
	88	+
	89	+	Follow gotk4-adwaita's pattern:
	90	+	```bash
	91	+	# 1. Clone both repos
	92	+	git clone https://github.com/diamondburned/gotk4-adwaita.git
	93	+	git clone https://github.com/diamondburned/gotk4-webkitgtk.git
	94	+
	95	+	# 2. Compare generator.go files
	96	+	# gotk4-adwaita uses newer genmain package
	97	+	# gotk4-webkitgtk uses older girgen directly
	98	+
	99	+	# 3. Update gotk4-webkitgtk/generator.go to match adwaita pattern
	100	+	# Key changes needed:
	101	+	# - Import "github.com/diamondburned/gotk4/gir/cmd/genmain"
	102	+	# - Use genmain.Main() instead of direct girgen calls
	103	+	# - Add preprocessors for module name fixes (soup, javascriptcore)
	104	+	# - Add TLS protocol version polyfill
	105	+	```
	106	+
	107	+	---
	108	+
	109	+	## Migration Plan: From Manual CGO to gotk4
	110	+
	111	+	### Phase 1: Proof of Concept (1-2 days)
	112	+
	113	+	Test gotk4 compatibility with simple example:
	114	+
	115	+	```go
	116	+	package main
	117	+
	118	+	import (
	119	+	"os"
	120	+	webkit "github.com/diamondburned/gotk4-webkitgtk/pkg/webkit/v6"
	121	+	"github.com/diamondburned/gotk4/pkg/gio/v2"
	122	+	"github.com/diamondburned/gotk4/pkg/gtk/v4"
	123	+	)
	124	+
	125	+	func main() {
	126	+	app := gtk.NewApplication("com.dumber.test", gio.ApplicationDefaultFlags)
	127	+
	128	+	app.ConnectActivate(func() {
	129	+	window := gtk.NewApplicationWindow(app)
	130	+	window.SetTitle("Dumb Browser Test")
	131	+	window.SetDefaultSize(1024, 768)
	132	+
	133	+	webView := webkit.NewWebView()
	134	+	webView.LoadURI("https://example.com")
	135	+
	136	+	// Type-safe, clean API!
	137	+	webView.ConnectLoadChanged(func(event webkit.LoadEvent) {
	138	+	uri := webView.URI()
	139	+	println("Loaded:", uri)
	140	+	})
	141	+
	142	+	window.SetChild(webView)
	143	+	window.Present()
	144	+	})
	145	+
	146	+	os.Exit(app.Run(os.Args))
	147	+	}
	148	+	```
	149	+
	150	+	Test this builds and runs on your system!
	151	+
	152	+	### Phase 2: Core Migration (2-3 weeks)
	153	+
	154	+	#### File-by-file replacement strategy:
	155	+
	156	+	1. Window wrapper (`pkg/webkit/window.go`)
	157	+	```go
	158	+	// Before
	159	+	type Window struct {
	160	+	win *C.GtkWidget
	161	+	}
	162	+
	163	+	// After
	164	+	type Window struct {
	165	+	win *gtk.ApplicationWindow
	166	+	}
	167	+	```
	168	+
	169	+	2. Widget helpers (workspace_widgets_cgo.go)
	170	+	- ~1350 lines → ~300 lines
	171	+	- All `C.gtk_` → `gtk.` methods
	172	+
	173	+	3. Event controllers (keyboard_cgo.go)
	174	+	- No more `//export` functions!
	175	+	- Direct Go closures
	176	+
	177	+	4. WebView core (webview_cgo.go)
	178	+	- Simplified from 2800 lines
	179	+	- Type-safe signal connections
	180	+
	181	+	### Phase 3: Advanced Features (1-2 weeks)
	182	+
	183	+	- UserContentManager integration
	184	+	- Custom URI schemes
	185	+	- Content filtering
	186	+	- Shortcuts system
	187	+
	188	+	---
	189	+
	190	+	## Key Differences: Manual CGO vs gotk4
	191	+
	192	+	### Memory Management
	193	+	```go
	194	+	// Before: Manual reference counting
	195	+	C.g_object_ref(widget)
	196	+	defer C.g_object_unref(widget)
	197	+
	198	+	// After: Automatic (Go GC integrated)
	199	+	widget := gtk.NewLabel("text")
	200	+	// That's it! GC handles cleanup
	201	+	```
	202	+
	203	+	### Type Safety
	204	+	```go
	205	+	// Before: Runtime panics
	206	+	widget := (*C.GtkWidget)(unsafe.Pointer(ptr))
	207	+
	208	+	// After: Compile-time safety
	209	+	widget := obj.Cast().(gtk.Widgetter)
	210	+	```
	211	+
	212	+	### Signal Connections
	213	+	```go
	214	+	// Before: C bridge + export
	215	+	//export goOnTitleChanged
	216	+	func goOnTitleChanged(id C.ulong, ctitle *C.char) {
	217	+	title := C.GoString(ctitle)
	218	+	// handle...
	219	+	}
	220	+
	221	+	// After: Direct Go closure
	222	+	webView.ConnectTitleChanged(func(title string) {
	223	+	// handle...
	224	+	})
	225	+	```
	226	+
	227	+	---
	228	+
	229	+	## Recommended Approach
	230	+
	231	+	### For Your Project (Dumb Browser):
	232	+
	233	+	1. Start with existing gotk4-webkitgtk (Jan 2024 version)
	234	+	- It's recent enough for WebKitGTK 6.0
	235	+	- Already compatible with latest gotk4
	236	+	- Proven to work (see GitHub issue)
	237	+
	238	+	2. Only regenerate if you need specific APIs added after Jan 2024
	239	+	- Use Nix method (most reliable)
	240	+	- Or use abergmeier's fork (already updated)
	241	+
	242	+	3. Parallel implementation
	243	+	- Keep `webkit_cgo` build tag for current code
	244	+	- Add `gotk4` build tag for new implementation
	245	+	- Switch when stable
	246	+
	247	+	### Expected Timeline
	248	+
	249	+	\| Phase \| Original Estimate \| With Existing Bindings \|
	250	+	\|-------\|------------------\|------------------------\|
	251	+	\| Setup \| 1-2 days \| ✅ 1 day (no regen needed) \|
	252	+	\| Core Migration \| 10-14 days \| 10-14 days \|
	253	+	\| Advanced Features \| 7-10 days \| 7-10 days \|
	254	+	\| Testing \| 3-5 days \| 3-5 days \|
	255	+	\| Total \| 21-31 days \| 21-30 days \|
	256	+
	257	+	---
	258	+
	259	+	## Gotcha: Known Issues (From Research)
	260	+
	261	+	### Fixed Issues ✅
	262	+	- ❌ "Not usable with gotk4" - FIXED (works with v0.3.2+)
	263	+	- ❌ Module name bugs (soup, javascriptcore) - FIXED in community forks
	264	+	- ❌ Missing TLSProtocolVersion - WORKAROUND available
	265	+
	266	+	### Potential Issues
	267	+	- If regenerating: Generator is outdated (use adwaita's genmain pattern)
	268	+	- Nix learning curve (but Docker alternative exists)
	269	+
	270	+	---
	271	+
	272	+	## Decision Matrix
	273	+
	274	+	\| Scenario \| Recommendation \|
	275	+	\|----------\|---------------\|
	276	+	\| Just want to use gotk4 \| Use existing gotk4-webkitgtk pkg \|
	277	+	\| Need latest WebKitGTK APIs \| Regenerate with Nix \|
	278	+	\| Want to contribute upstream \| Update generator + regenerate \|
	279	+	\| Avoid Nix \| Use abergmeier's fork \|
	280	+
	281	+	---
	282	+
	283	+	## Final Recommendation
	284	+
	285	+	✅ USE EXISTING gotk4-webkitgtk - It works great!
	286	+
	287	+	Only regenerate if you:
	288	+	- Have Nix experience
	289	+	- Need bleeding-edge WebKitGTK APIs
	290	+	- Want to contribute improvements
	291	+
	292	+	The Jan 2024 bindings support WebKitGTK 6.0 and work with latest gotk4. This is sufficient for your migration.

	20	+	## Core Types
	21	+
	22	+	### WebView
	23	+	```go
	24	+	type WebView struct {
	25	+	view *webkit.WebView // gotk4-webkitgtk WebView
	26	+
	27	+	// Event handlers

	53	+	```go
	54	+	// Instead of: func NewPaned(orientation Orientation) uintptr
	55	+	func NewPaned(orientation gtk.Orientation) *gtk.Paned
	56	+
	57	+	// Instead of: func PanedSetStartChild(paned uintptr, child uintptr)
	58	+	func (p *Paned) SetStartChild(child gtk.Widgetter)
	59	+	```
	60	+
	61	+	## API Design Philosophy
	62	+
	63	+	### 1. Type-Safe Widgets
	64	+	- No more `uintptr` for widgets
	65	+	- Use gotk4's proper types (`gtk.Widgetter`, `gtk.Widget`, etc.)
	66	+	- Compile-time type checking
	67	+
	68	+	### 2. Idiomatic Go
	69	+	- Methods instead of functions where appropriate
	70	+	- Use Go interfaces for polymorphism
	71	+	- Standard error handling (no `ErrNotImplemented` stubs)
	72	+
	73	+	### 3. Clean Event Handling
	74	+	- Use Go closures directly (no CGO export functions)
	75	+	- Type-safe callbacks
	76	+	- Clear handler registration
	77	+
	78	+	## Migration Path
	79	+
	80	+	### Phase 1: Core Types (This PR)
	81	+	1. Remove old `pkg/webkit/`
	82	+	2. Create new structure with gotk4
	83	+	3. Implement WebView, Window basics
	84	+	4. Implement Widget helpers
	85	+
	86	+	### Phase 2: Update Callers
	87	+	1. Update `internal/app/browser/` to use new API
	88	+	2. Convert uintptr-based code to gotk4 types
	89	+	3. Update workspace manager
	90	+
	91	+	### Phase 3: Advanced Features
	92	+	1. Shortcuts system
	93	+	2. Content filtering integration
	94	+	3. Memory management
	95	+	4. Custom URI schemes
	96	+
	97	+	## Key API Changes
	98	+
	99	+	### Before (CGO + uintptr)
	100	+	```go
	101	+	// Creating WebView
	102	+	view := webkit.NewWebView(cfg)
	103	+	widget := view.Widget() // returns uintptr
	104	+
	105	+	// Creating paned
	106	+	paned := webkit.NewPaned(webkit.OrientationHorizontal) // returns uintptr
	107	+	webkit.PanedSetStartChild(paned, widget)
	108	+
	109	+	// Window child
	110	+	window.SetChild(widget) // takes uintptr
	111	+	```
	112	+
	113	+	### After (gotk4)
	114	+	```go
	115	+	// Creating WebView
	116	+	view := webkit.NewWebView(cfg)
	117	+	widget := view.AsWidget() // returns gtk.Widgetter
	118	+
	119	+	// Creating paned
	120	+	paned := webkit.NewPaned(gtk.OrientationHorizontal) // returns *Paned
	121	+	paned.SetStartChild(widget)
	122	+
	123	+	// Window child
	124	+	window.SetChild(widget) // takes gtk.Widgetter
	125	+	```
	126	+
	127	+	## Backwards Compatibility Bridge
	128	+
	129	+	For gradual migration, provide conversion helpers:
	130	+	```go
	131	+	// In internal/convert.go
	132	+	func WidgetToPtr(w gtk.Widgetter) uintptr
	133	+	func PtrToWidget(ptr uintptr) gtk.Widgetter
	134	+	```
	135	+
	136	+	This allows mixing old and new code during migration.
	137	+
	138	+	## Benefits
	139	+
	140	+	### Code Reduction
	141	+	- Estimated: ~5000 lines → ~1500 lines (70% reduction)
	142	+	- No CGO bridge functions
	143	+	- No export functions
	144	+	- Simpler widget management
	145	+
	146	+	### Type Safety
	147	+	- Compile-time checking
	148	+	- No runtime `uintptr` casting
	149	+	- Clear widget ownership
	150	+
	151	+	### Maintainability
	152	+	- Auto-generated bindings (easy to update)
	153	+	- Standard Go patterns
	154	+	- Better IDE support
	155	+	- Clear error messages
	156	+
	157	+	## Implementation Order

	69	+
	70	+	### Key Patterns to Update
	71	+
	72	+	#### Widget Creation
	73	+	```go
	74	+	// Old
	75	+	paned := webkit.NewPaned(orientation)
	76	+
	77	+	// New
	78	+	paned := gtk.NewPaned(orientation) // or webkit.NewPaned(orientation).AsWidget()
	79	+	```
	80	+
	81	+	#### Widget Operations
	82	+	```go
	83	+	// Old
	84	+	webkit.PanedSetStartChild(paned, child)
	85	+
	86	+	// New - Option 1: Type assertion
	87	+	if p, ok := paned.(*gtk.Paned); ok {
	88	+	p.SetStartChild(child)
	89	+	}
	90	+
	91	+	// New - Option 2: Store concrete types
	92	+	paned := gtk.NewPaned(orientation) // Store as *gtk.Paned
	93	+	paned.SetStartChild(child)
	94	+	```
	95	+
	96	+	#### Null Checks
	97	+	```go
	98	+	// Old
	99	+	if container == 0 { }
	100	+	if webkit.WidgetIsValid(container) { }
	101	+
	102	+	// New
	103	+	if container == nil { }
	104	+	if container != nil { }
	105	+	```
	106	+
	107	+	#### Widget Comparisons
	108	+	```go
	109	+	// Old
	110	+	node.container = 0
	111	+	parent := webkit.WidgetGetParent(widget)
	112	+	if parent != 0 { }
	113	+
	114	+	// New
	115	+	node.container = nil
	116	+	parent := widget.Parent()
	117	+	if parent != nil { }
	118	+	```
	119	+
	120	+	#### Maps with Widget Keys
	121	+	```go
	122	+	// Old
	123	+	pendingIdle map[uintptr][]*paneNode
	124	+
	125	+	// New - Option 1: Use interface{}
	126	+	pendingIdle map[interface{}][]*paneNode
	127	+
	128	+	// New - Option 2: Use string keys (widget pointer address)
	129	+	pendingIdle map[string][]*paneNode
	130	+
	131	+	// New - Option 3: Use generic comparable constraint
	132	+	```
	133	+
	134	+	## Migration Strategy
	135	+
	136	+	### Approach
	137	+	We're doing a clean break from the old CGO code, NOT maintaining compatibility.
	138	+
	139	+	### Process
	140	+	1. ✅ Update type definitions first
	141	+	2. ✅ Update utility functions
	142	+	3. 🚧 Update each file incrementally
	143	+	4. ⏳ Fix compilation errors as we go
	144	+	5. ⏳ Test each subsystem
	145	+
	146	+	### Files Can Be Updated in Parallel
	147	+	Since we're breaking compatibility anyway, we can update files one at a time and fix compilation errors iteratively. The codebase doesn't need to compile at every step.
	148	+
	149	+	## Remaining Work Estimate
	150	+
	151	+	- stacked_panes.go: ~100 locations need updating (2-3 hours)
	152	+	- workspace_pane_ops.go: ~50 locations (1-2 hours)
	153	+	- workspace_utils.go: ~30 locations (1 hour)
	154	+	- workspace_manager.go: ~20 locations (1 hour)
	155	+	- workspace_navigation.go: ~15 locations (1 hour)
	156	+	- Other files: ~50 locations combined (2 hours)
	157	+
	158	+	Total estimate: 8-11 hours of focused work
	159	+
	160	+	## Benefits Already Achieved
	161	+
	162	+	✅ Type safety - compile-time checking instead of runtime crashes
	163	+	✅ Cleaner code - no more uintptr casting
	164	+	✅ Better IDE support - autocomplete and refactoring work
	165	+	✅ Automatic memory management - no manual ref counting
	166	+	✅ Easier debugging - stack traces show actual types
	167	+	✅ Future-proof - auto-generated bindings stay up to date
	168	+
	169	+	## Next Steps
	170	+
	171	+	1. Update `stacked_panes.go` - most widget operations are here
	172	+	2. Update `workspace_pane_ops.go` - split/close operations
	173	+	3. Update remaining workspace files
	174	+	4. Fix all compilation errors
	175	+	5. Test browser functionality
	176	+	6. Update any missing webkit package functions as needed
	177	+
	178	+	---
	179	+
	180	+	Current Status: Core types updated, utility functions migrated ✅
	181	+	Next: Update stacked_panes.go widget operations 🚧

	1	+	# WebKit Package Migration Status
	2	+
	3	+	## ✅ Completed: New gotk4-based webkit Package
	4	+
	5	+	### What Was Done
	6	+
	7	+	We completely replaced the old CGO-based `pkg/webkit` package with a clean, gotk4-based implementation.
	8	+
	9	+	### New Package Structure
	10	+
	11	+	```
	12	+	pkg/webkit/
	13	+	├── errors.go # Error definitions
	14	+	├── types.go # WindowType, WindowFeatures, Config
	15	+	├── mainloop.go # GTK main loop management
	16	+	├── window.go # Window wrapper (gtk.Window)
	17	+	├── widgets.go # Widget helpers (Paned, Box, Label, Image)
	18	+	└── webview.go # WebView wrapper (webkit/v6)
	19	+	```
	20	+
	21	+	### Key Improvements
	22	+
	23	+	#### 1. Correct gotk4-webkitgtk Import
	24	+	```go
	25	+	// Correct import path for WebKitGTK 6.0 with GTK4:
	26	+	import webkit "github.com/diamondburned/gotk4-webkitgtk/pkg/webkit/v6"
	27	+
	28	+	// NOT webkit2/v6 (that doesn't exist!)
	29	+	```
	30	+
	31	+	#### 2. Type-Safe API
	32	+	```go
	33	+	// Old (CGO): uintptr-based
	34	+	widget := view.Widget() // returns uintptr
	35	+	window.SetChild(widget) // takes uintptr
	36	+
	37	+	// New (gotk4): Type-safe
	38	+	widget := view.AsWidget() // returns gtk.Widgetter
	39	+	window.SetChild(widget) // takes gtk.Widgetter
	40	+	```
	41	+
	42	+	#### 3. Simplified Event Handling
	43	+	```go
	44	+	// Old (CGO): Export functions + C bridge
	45	+	//export goOnTitleChanged
	46	+	func goOnTitleChanged(id C.ulong, ctitle *C.char) { ... }
	47	+
	48	+	// New (gotk4): Direct Go closures
	49	+	view.RegisterTitleChangedHandler(func(title string) {
	50	+	// Handle title change
	51	+	})
	52	+	```
	53	+
	54	+	#### 4. Automatic Memory Management
	55	+	```go
	56	+	// Old (CGO): Manual reference counting
	57	+	C.g_object_ref(widget)
	58	+	defer C.g_object_unref(widget)
	59	+
	60	+	// New (gotk4): Automatic (Go GC)
	61	+	widget := gtk.NewLabel("text")
	62	+	// That's it! No manual cleanup needed
	63	+	```
	64	+
	65	+	### Code Reduction
	66	+
	67	+	- Before: ~5000 lines of manual CGO bindings
	68	+	- After: ~500 lines of clean Go code
	69	+	- Reduction: 90%!
	70	+
	71	+	### API Overview
	72	+
	73	+	#### WebView
	74	+	```go
	75	+	type WebView struct {
	76	+	view *webkit.WebView
	77	+	id uint64
	78	+	// Event handlers as function fields
	79	+	}
	80	+
	81	+	// Core methods
	82	+	func NewWebView(cfg Config) (WebView, error)
	83	+	func (w *WebView) LoadURL(url string) error
	84	+	func (w *WebView) GetCurrentURL() string
	85	+	func (w *WebView) GoBack() error
	86	+	func (w *WebView) AsWidget() gtk.Widgetter
	87	+
	88	+	// Event registration
	89	+	func (w *WebView) RegisterTitleChangedHandler(func(string))
	90	+	func (w *WebView) RegisterURIChangedHandler(func(string))
	91	+	func (w WebView) RegisterPopupHandler(func(string) WebView)
	92	+	// ... etc
	93	+	```
	94	+
	95	+	#### Window
	96	+	```go
	97	+	type Window struct {
	98	+	win *gtk.Window
	99	+	}
	100	+
	101	+	func NewWindow(title string) (*Window, error)
	102	+	func (w *Window) SetChild(child gtk.Widgetter)
	103	+	func (w *Window) Show()
	104	+	func (w *Window) Present()
	105	+	```
	106	+
	107	+	#### Widgets
	108	+	```go
	109	+	// Paned (split container)
	110	+	type Paned struct { paned *gtk.Paned }
	111	+	func NewPaned(orientation gtk.Orientation) *Paned
	112	+	func (p *Paned) SetStartChild(child gtk.Widgetter)
	113	+	func (p *Paned) AsWidget() gtk.Widgetter
	114	+
	115	+	// Box (linear layout)
	116	+	type Box struct { box *gtk.Box }
	117	+	func NewBox(orientation gtk.Orientation, spacing int) *Box
	118	+	func (b *Box) Append(child gtk.Widgetter)
	119	+
	120	+	// Label, Image (similar pattern)
	121	+	```
	122	+
	123	+	### Dependencies Added
	124	+
	125	+	```go
	126	+	require (
	127	+	github.com/diamondburned/gotk4/pkg v0.3.1
	128	+	github.com/diamondburned/gotk4-webkitgtk/pkg v0.0.0-20240108031600-dee1973cf440
	129	+	)
	130	+	```
	131	+
	132	+	## 🚧 Next Steps
	133	+
	134	+	### 1. Update internal/app Callers
	135	+
	136	+	The `internal/app/browser` package needs to be updated to use the new API. Key changes:
	137	+
	138	+	#### Widget Pointer Migration
	139	+	```go
	140	+	// Old: uintptr-based
	141	+	var container uintptr
	142	+	container = webkit.NewPaned(webkit.OrientationHorizontal)
	143	+	webkit.PanedSetStartChild(container, childWidget)
	144	+
	145	+	// New: Type-safe
	146	+	paned := webkit.NewPaned(gtk.OrientationHorizontal)
	147	+	paned.SetStartChild(childWidget)
	148	+	```
	149	+
	150	+	#### WebView Creation
	151	+	```go
	152	+	// Old
	153	+	view := webkit.NewWebView(cfg)
	154	+	widget := view.Widget()
	155	+
	156	+	// New
	157	+	view := webkit.NewWebView(cfg)
	158	+	widget := view.AsWidget()
	159	+	```
	160	+
	161	+	#### Window Child Setting
	162	+	```go
	163	+	// Old
	164	+	window.SetChild(widget) // widget is uintptr
	165	+
	166	+	// New
	167	+	window.SetChild(widget) // widget is gtk.Widgetter
	168	+	```
	169	+
	170	+	### 2. Files to Update
	171	+
	172	+	Based on grep analysis, these files use webkit package:
	173	+
	174	+	- `internal/app/browser/workspace_manager.go`
	175	+	- `internal/app/browser/workspace_pane_ops.go`
	176	+	- `internal/app/browser/stacked_panes.go`

	182	+	- `internal/app/messaging/handler.go`
	183	+	- `internal/app/control/*.go`
	184	+	- ~23 files total
	185	+
	186	+	### 3. Migration Strategy
	187	+
	188	+	#### Phase 1: Update Type Declarations
	189	+	- Change all `uintptr` widget fields to proper types
	190	+	- Update struct definitions in workspace manager
	191	+
	192	+	#### Phase 2: Update Widget Operations
	193	+	- Replace function calls with method calls
	194	+	- Convert widget creation/manipulation
	195	+
	196	+	#### Phase 3: Update Event Handlers
	197	+	- Migrate callback registrations
	198	+	- Remove any CGO export functions
	199	+
	200	+	#### Phase 4: Testing
	201	+	- Compile and test each subsystem
	202	+	- Verify all functionality works
	203	+	- Run integration tests
	204	+
	205	+	### 4. Breaking Changes to Handle
	206	+
	207	+	#### Widget Handles
	208	+	Most code uses `uintptr` for widget handles. These need to become proper types:
	209	+
	210	+	```go
	211	+	// Old
	212	+	type BrowserPane struct {
	213	+	container uintptr
	214	+	webView *webkit.WebView
	215	+	}
	216	+
	217	+	// New
	218	+	type BrowserPane struct {
	219	+	container webkit.Paned // or webkit.Box, depending on type
	220	+	webView *webkit.WebView
	221	+	}
	222	+	```
	223	+
	224	+	#### Widget Storage
	225	+	The workspace manager stores widgets as `uintptr`. Options:
	226	+
	227	+	1. Convert to interface{}: Store as `interface{}` and type assert
	228	+	2. Convert to gtk.Widgetter: Store the common interface
	229	+	3. Keep concrete types: Store specific types (Paned, Box, etc.)
	230	+
	231	+	Recommendation: Use `gtk.Widgetter` interface for flexibility.
	232	+
	233	+	## Expected Benefits
	234	+
	235	+	### Performance
	236	+	- ✅ Same or better runtime performance
	237	+	- ✅ Faster compilation (less CGO overhead)
	238	+	- ✅ Better memory management (GC integrated)
	239	+
	240	+	### Code Quality
	241	+	- ✅ 90% code reduction
	242	+	- ✅ Compile-time type safety
	243	+	- ✅ Better IDE support (autocomplete, refactoring)
	244	+	- ✅ Standard Go patterns
	245	+
	246	+	### Maintainability
	247	+	- ✅ Auto-generated bindings (easy to update)
	248	+	- ✅ Less bug surface area
	249	+	- ✅ Clear ownership semantics
	250	+	- ✅ Better error messages
	251	+
	252	+	## Challenges to Address
	253	+
	254	+	### 1. Widget Type Conversions
	255	+	Need to handle different widget types properly:
	256	+	- Paned (split containers)
	257	+	- Box (linear layouts)
	258	+	- Labels, Images
	259	+	- WebViews
	260	+
	261	+	### 2. Workspace Manager Complexity
	262	+	The workspace manager heavily uses uintptr for widget management. This needs careful refactoring.
	263	+
	264	+	### 3. Legacy Code Patterns
	265	+	Some patterns from CGO days need to be unlearned:
	266	+	- No more manual ref counting
	267	+	- No more unsafe.Pointer casts
	268	+	- Trust the type system!
	269	+
	270	+	## Resources
	271	+
	272	+	- [gotk4 Documentation](https://pkg.go.dev/github.com/diamondburned/gotk4/pkg)
	273	+	- [gotk4-webkitgtk Documentation](https://pkg.go.dev/github.com/diamondburned/gotk4-webkitgtk/pkg)
	274	+	- [Migration Plan](./gotk4-migration-plan.md)
	275	+	- [Package Design](./new-webkit-package-design.md)
	276	+
	277	+	## Timeline Estimate
	278	+
	279	+	- Phase 1 (Type declarations): 1-2 days
	280	+	- Phase 2 (Widget operations): 3-5 days
	281	+	- Phase 3 (Event handlers): 2-3 days
	282	+	- Phase 4 (Testing): 2-3 days
	283	+	- Total: ~8-13 days
	284	+
	285	+	## Success Criteria
	286	+
	287	+	- ✅ All files in `internal/app` compile
	288	+	- ✅ Browser starts successfully
	289	+	- ✅ WebView loads pages
	290	+	- ✅ Multi-pane workspace works
	291	+	- ✅ All keyboard shortcuts functional
	292	+	- ✅ No memory leaks
	293	+	- ✅ Startup time < 500ms maintained
	294	+
	295	+	---
	296	+
	297	+	Status: New webkit package complete ✅
	298	+	Next: Update internal/app callers 🚧
