Update CHANGELOG and automate releases

- Add CHANGELOG entry for version 2.2.0
- Add create-release job to auto-create GitHub releases on tag push
- Change publish-to-pypi to trigger on tag push (not release event)
- Auto-generate release notes and attach build artifacts

The release process is now fully automated: push a tag and the
workflow will build, test, create a GitHub release, and publish to PyPI.
