Setup changesets for automated release management

- Add @changesets/cli for semantic versioning and changelog generation
- Configure changesets with public access for npm publishing
- Add npm scripts: changeset, version-packages, release
- Create GitHub Action for automated release workflow
- Enables structured release process with user-friendly changelogs

Usage:
- pnpm changeset (create changeset for your changes)
- pnpm version-packages (bump versions and update changelog)
- pnpm release (build and publish to npm)
