MVP built at offloadmywork/openclaw-github-app. Architecture: GitHub Actions runtime + Actions Cache for state + Cron for heartbeats. Next steps: (1) Set up a test repo with the action configured, (2) Test all trigger types (heartbeat cron, issue opened, PR opened, @mention in comments), (3) Fix issues found during testing, (4) Document setup instructions in README. Priority: P0, Owner: Offload, Status: In Progress
