Address PR Comments

Overview

Collect PR feedback with gh, classify AI/bot vs human comments, validate each comment against current code, implement only valid changes, and summarize what was addressed vs rejected.

Workflow

Address PR comments in this order:

1. Resolve target PR.
2. Verify gh availability/auth.
3. Collect comments (top-level, reviews, inline).
4. Classify source (AI/bot vs human).
5. Validate each comment before changing code.
6. Apply fixes and run targeted checks.
7. Commit each resolved comment locally (no push).
8. Summarize addressed/rejected items with rationale.
