- Add integration test for status-guarded contract inference
- Tighten and deduplicate docs across verify, qualify, getting-started, cli
- Fix broken cross-references and TypeScript→JavaScript conversions

- Add missing features: --workspace, --generation-profile, json-summary formats
- Move stale extension docs (AUTH-RATE-LIMIT-REVISED, HTTP-EXTENSIONS) to attic
- Update PLUGIN_CONTRACTS_SPEC status to Implemented
- Build: clean | Tests: 849 pass, 0 fail
