Restore PR title validation that was removed in 828f33a when
cdr-bot was expected to handle it. That bot has since been disabled.
The new title job in contrib.yaml validates:
- Conventional commit format (type(scope): description)
- Type from the same set used by release notes generation
- Scope validity derived from the changed files in the PR diff
- All changed files fall under the declared scope
Uses actions/github-script (no third-party marketplace actions).
Also fixes feat(api) examples across docs (no api folder exists)
and consolidates commit rules into CONTRIBUTING.md as the single
source of truth.
Replace `.cursorrules` with symlink to `AGENTS.md` to establish a single
authoritative document for AI agent guidelines.
Extract architectural documentation from `.cursorrules` into
`.claude/docs/ARCHITECTURE.md` for reference material.
This ensures all AI agents (Claude, Cursor, etc.) use the same
guidelines without duplication.
