chore: add workflow to auto-move project items to Done on close/merge (#165)

- New workflow project-auto-done.yml triggers on issue close and PR merge
- Uses GraphQL to find the project item and update Status to Done
- Handles both issues and pull requests with proper type detection
- Skips gracefully if item is not on the board or already Done
- Update release-manager.agent.md to reflect automation (manual is now fallback)
