feat(sw): prepare reusable AI-friendly component package

- Ship an AI guide in the package (ai/: usage rules, component catalog,
  design rules, composition patterns) via package.json files.
- Add examples A-D that import only public exports: default header,
  viewer header, feature header, and a consumer-side search extension
  that reuses SWHeaderInput and the public SW tokens.
- Add SW-only checks: docs/API consistency, tarball consumer project
  (React 19 + TS + Vite typecheck/build) and a browser check (27/27).
- No runtime source or public API change; README gains a pointer section.
