* [AI] Add AI Usage Policy for contributors
Add a contributor-facing AI Usage Policy page modeled on ESLint's version,
covering disclosure, human-only interaction with maintainers, and author
responsibility. Wire it into the docs sidebar, link it from the contributing
index and the root CONTRIBUTING.md.
