PR Review Skill

1. •Fetch all open review comments: gh api repos/{owner}/{repo}/pulls/{pr}/comments
2. •Group comments by severity (CRITICAL, HIGH, MEDIUM, LOW)
3. •Fix CRITICAL and HIGH issues first, one commit per logical fix
4. •Reply to each resolved comment using gh api repos/{owner}/{repo}/pulls/{pr}/comments -f body="Fixed: <description>" -F in_reply_to=<comment_id>
5. •Run full test suite after all fixes
6. •Push and summarize remaining unresolved items

IMPORTANT: Use in_reply_to parameter for reply threading. Do NOT use issues/comments endpoint.
