google-labs-jules[bot] 1b82a2865d Optimize branch analysis in PR review script
- Modified `scripts/review_pull_requests.py` to filter `git for-each-ref` output by unmerged branches.
- Reduces algorithmic complexity from O(N) to O(M) where N is total branches and M is active branches.
- Avoids expensive `ahead-behind` calculations for potentially thousands of stale merged branches.
