Add review loop and concise summary to issue-worker agent

- Add Task tool to spawn code-reviewer synchronously
- Add review loop: fix issues and re-review until approved (max 3 iterations)
- Add final summary format for cleaner output to spawning process
- Reviewer works in same worktree, cleanup only after review completes

+### 6. Review Loop
+
+Spawn the `code-reviewer` agent **synchronously** to review the PR in the current worktree:
+
+```
+Task tool with:
+  - subagent_type: "code-reviewer"
+  - run_in_background: false
+  - prompt: "Review PR #<PR_NUMBER>. Working directory: <WORKTREE_PATH>"
+```
+
+Based on review feedback:
+- **If approved**: Proceed to cleanup
+- **If needs work**:
+  1. Address the review feedback
+  2. Commit and push the fixes
+  3. Trigger another review
+  4. Repeat until approved (max 3 iterations to avoid infinite loops)

+### 7. Cleanup Worktree

+### 8. Final Summary
+
+**IMPORTANT**: Your final output must be a concise summary (5-10 lines max) for the spawning process:
+
+```
+Issue #<NUMBER>: <title>
+Status: <completed|partial|blocked>
+PR: #<PR_NUMBER> (<url>)
+Changes: <1-2 sentence summary>
+Review: <approved|needs-work|skipped>
+Notes: <any blockers or important details>
+```
+
+Do NOT include verbose logs or intermediate output - only this final summary.
+
 ## Important Guidelines
 
 - **Work autonomously**: Make reasonable judgment calls on ambiguous requirements
