Triage PR Review Comments

1. Run gh pr-reviews [arg] --json to get unresolved review comments as JSON. If no argument is given, use the current branch's PR. Note: this command uses Copilot for classification and may take a while depending on the number of comments — use a longer timeout. Each JSON object contains:
   • comment_id (int): REST API comment ID — usable for replying via gh api
   • thread_id (string, only for type: "thread"): inline review thread ID
   • type: "thread" (inline review) or "comment" (PR-level)
   • author, body, url: comment metadata
   • commit_id, path, line, diff_hunk (only for type: "thread"): file location and diff context
   • category: one of suggestion, nitpick, issue, question, approval, informational
   • resolved (bool), reason (string): resolution status and rationale
2. Check if PR metadata (number, title, url) is already available from conversation context. If not (e.g., when a PR number/URL is explicitly passed as argument), run gh pr view [arg] --json number,title,url to get it.
3. For type: "thread" comments, use path, line, and diff_hunk from the JSON response to identify the exact file location. For type: "comment" (PR-level), there is no file location.
4. Check code context for each comment. Leverage any existing conversation context first. Only fetch additional context via gh pr diff or file reads when necessary.
5. Evaluate each comment against the code context. Classify as Agree, Partially Agree, or Disagree with a rationale and suggested action.
6. Output results in this format:

## Unresolved Review Comments Analysis

**PR**: #<number> (<title>)
**Unresolved comments**: <count>

---

### Comment 1 — [<category>] by @<author>
> <comment body>

**File**: `<path>` (line <line>)
**Assessment**: Agree | Partially Agree | Disagree
**Rationale**: <1-3 sentences>
**Suggested action**: <recommended action>

---

## Summary
- Agree: n — should be addressed
- Partially Agree: n — worth discussing
- Disagree: n — can be explained or dismissed

Do NOT write to GitHub (no commenting, resolving, or any mutations). Do NOT commit or push. If code context is unclear, search the codebase to verify before making a judgment. Prefer gh commands for GitHub data.
