autofix-pr: does not resolve PR review conversations after applying fixes

Summary

When using autofix-pr (or /code-review --fix) to apply fixes from PR review comments, Claude applies the code changes but does not resolve the corresponding PR review conversations/threads.

Steps to Reproduce

1. Open a PR with review comments requesting changes
2. Run Claude Code's autofix-pr flow to apply the suggested fixes
3. Observe that the PR review threads remain open/unresolved

Expected Behavior

After applying fixes that address a review comment, Claude should resolve the corresponding PR conversation thread automatically (same as clicking "Resolve conversation" on GitHub).

Actual Behavior

All review threads remain unresolved after autofix-pr completes. User must manually prompt Claude to resolve each thread, or resolve them by hand on GitHub.

Workaround

Manually ask Claude: "resolve the PR conversations" after autofix-pr finishes.

Environment

• Tool: Claude Code CLI / autofix-pr / /code-review --fix
• Claude Code version: 2.1.170
• Platform: macOS
• PR review source: GitHub Copilot PR reviews

Additional Context

Tested specifically against PRs reviewed by GitHub Copilot — Copilot leaves inline review comments/threads, autofix-pr applies the fixes but leaves all Copilot threads unresolved.

Resolving conversations is possible via GitHub API (PUT /repos/{owner}/{repo}/pulls/comments/{comment_id}/replies or marking threads as resolved). The fix would be to call the resolve-conversation API for each thread whose comment was addressed by the applied patch.
