feat(web): add commit page with unified and split diffs

/<repo>/commit/<sha> (full or abbreviated id): message, author and
committer, parent links, refs, totals, the file list in the rail and the
diff of each file in a <details>. Unified is the default; ?view=split
selects the split layout on the server, and the toggle links work without
JavaScript (with it, both layouts are in the page and d/u/x flip them).
Truncated and binary files are collapsed under a note, renames, copies and
mode changes are noted, an incomplete diff says so. Invisible characters
(bidi controls, zero-width, controls) show as <U+XXXX> markers; every
changed line keeps its +/- marker.
