feat(provider): add Claude Opus 4.8 to anthropic + bedrock + gateway catalogs

Anthropic shipped claude-opus-4-8 today (2026-05-28). Pricing and
limits are identical to the 4.7 line per models.dev:

  - 1,000,000 token context window
  - 128,000 token max output
  - reasoning supported
  - $5.00 / $25.00 per 1M input/output tokens
  - $0.50 / $6.25 per 1M cache read/write tokens

Mirror the same provider topology zot already uses for 4.5, 4.6, and
4.7, so the new model shows up everywhere users have an existing
Opus route configured:

  - packages/provider/models.go: anthropic (speculative block,
    matching how 4.5/4.6/4.7 are listed)
  - packages/provider/catalog_builtin.go:
      * amazon-bedrock: anthropic.claude-opus-4-8 plus the five
        regional cross-region inference profiles
        (us./eu./global./jp./au.). AU keeps its 3.3x surcharge
        ($16.50 / $82.50) consistent with 4.6/4.7 AU rows.
      * cloudflare-ai-gateway
      * github-copilot (Copilot pricing is $0/$0, ctx 144k,
        output 64k, matching the 4.7 Copilot row)
      * opencode
      * openrouter: standard route plus the 6x 'Fast' SKU
        ($30/$150/$3/$37.50) consistent with 4.6/4.7
      * vercel-ai-gateway

Vertex (google-vertex / google-vertex-anthropic) is deliberately
skipped: zot's google-vertex provider is Gemini-only today and there
is no google-vertex-anthropic provider wired up. Earlier Opus
versions skip Vertex for the same reason, so 4.8 stays consistent.

Tests:
  - go build ./... clean
  - go vet ./packages/provider/... clean
  - go test ./packages/provider/... pass
