Replace changesets with a simple, stateless release system:
Stable release (PR-gated):
Actions → "create release PR" → pick patch/minor/major → CI runs →
merge → publishes to npm, creates git tag + GitHub Release
Prerelease (ad-hoc):
Actions → "publish / prerelease" → publishes current version with
-canary.<suffix|timestamp> to npm under "canary" tag
Key features:
- All 12 core @copilotkit/* packages share a single version
- AI-generated release notes via Anthropic API
- Notion draft for team editing before merge
- Notion link commented on the release PR
- Guards: concurrent release PR check, version > npm check, clean
semver check, canary-only prerelease tag
- release/publish/v* branch pattern (hard to accidentally match)
- TypeScript throughout (tsx runner)
- release.config.json with versionedTogether/versionedIndependently
