- Add automatic cleanup of old Claude comments after each review
- Create reusable cleanup script that intelligently handles different comment types
- Keep only the most recent successful review visible
- Collapse (not delete) old reviews, errors, and status messages
- Add manual cleanup workflow that can be triggered or run on schedule
- Preserve comment history while keeping PRs readable
This solves the issue where Claude creates new comments instead of updating
existing ones, since the anthropics/claude-code-action@beta doesn't support
comment updates natively.
