Greptile Summary

Adds a new list_recent_unresolved MCP tool that scans recently merged PRs for unresolved review threads, addressing the blind spot where late-arriving reviewer comments on already-merged PRs go unnoticed by agents.

• New _fetch_merged_prs() helper fetches merged PRs via gh pr list --state merged, capped at 50
• list_recent_unresolved() iterates merged PRs, reuses existing _fetch_pr_summary() GraphQL query, and filters to only PRs with unresolved threads
• Returns StackReviewStatusResult — zero new models, consistent with summarize_review_status
• MCP tool registered in server.py with proper error handling and workspace detection
• 7 new tests covering filtering, empty states, auto-detection, progress reporting, and CLI argument passing
• Integration test updated to expect 12 tools

Confidence Score: 4/5

• This PR is safe to merge — clean additive feature with good test coverage and no breaking changes.
• The implementation is well-structured, follows existing codebase patterns exactly, reuses existing models and helpers, and has comprehensive test coverage. No new dependencies or breaking changes. The only minor concern is the sequential GraphQL calls for each merged PR (no concurrency), but this matches the existing pattern in summarize_review_status.
• No files require special attention.
