Address critical and important issues from spec review:
- Use pull_request_target instead of pull_request for fork write access
- Remove approval step (GITHUB_TOKEN can't self-approve)
- Add duplicate check against open/closed PRs
- Add reopened/edited event types
- Skip auto-merge for entries with no GitHub URL
- Clarify urllib.request usage and 365-day activity window
- Note deliberate deviation from CONTRIBUTING.md auto-close behavior
