🧹 [코드 퀄리티 향상] inspect_pr 함수 복잡도 완화

[seonghobae]

🎯 What: scripts/ci/pr_review_merge_scheduler.py 파일의 inspect_pr 함수의 복잡도가 너무 높아 유지보수가 어려웠던 점을 개선했습니다.
💡 Why: 코드가 300줄이 넘어가는 단일 함수로 이루어져 가독성이 떨어지고, 수정 시 버그 발생 위험이 매우 높았습니다. 이를 'Replace Method with Method Object' 디자인 패턴을 활용하여 _PRInspector라는 내부 클래스로 캡슐화하고 각 주요 로직들을 10여 개의 작은 private 메소드(_handle_stacked_pr 등)로 분리했습니다.
✅ Verification: 모든 테스트 스위트를 100% 통과(pytest)했으며 flake8의 McCabe 복잡도 검사(C901)의 높은 복잡도 경고가 해결됨을 확인했습니다.
✨ Result: 기존 사용자나 외부 함수 호출 서명(def inspect_pr)에 전혀 영향을 주지 않으면서 내부 구현만 깔끔하게 객체지향적으로 분리되어 코드 가독성과 유지보수성이 크게 향상되었습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 35 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

RCA/feasibility: closing unmerged as superseded by the active scheduler safety architecture. PR #828 replaces the pre-existing monolithic pr_review_merge_scheduler.py with a small auditable independent-approval policy facade plus scripts/ci/_pr_review_merge_scheduler_core.py, and changes the exact merge-authorization contract at the same time. This PR refactors the old monolithic inspect_pr implementation into a method object on protected-main shape, adding ~470/-326 lines without fixing a distinct current defect. Applying it before #828 would create immediate structural conflict and applying it after #828 would require redesign against the new core anyway. Complexity work should be measured and reconsidered only on the protected architecture after #828 integrates; it must not compete with the security-boundary writer.

Understood. Acknowledging that this work is now obsolete and stopping work on this task.
