r2

Publish a new release of the R2 Client desktop app and monitor CI. Use when the user asks to "publish a release", "cut a release", "bump the version", "release a new version", "check ci" after changes are committed, or "write release notes" / "publish release notes". Handles pre-flight checks, version bumping, git tagging, pushing, CI monitoring, and generating release notes from git diff using the project's publish.sh script and the gh CLI.
