⚡ Bolt: [성능 개선] GitHub API 요청 병렬화

[seonghobae]

💡 What: current_head_run_coalescer.py에서 _fetch_pr 및 _fetch_run을 호출할 때 발생하는 N+1 API 병목 현상을 concurrent.futures.ThreadPoolExecutor를 사용하여 병렬로 처리하도록 개선했습니다.

🎯 Why: 여러 개의 PR이나 워크플로우 실행을 순차적으로 가져오면 네트워크 I/O 병목이 발생하여 전체 실행 시간이 크게 증가합니다. 이를 병렬화하여 성능을 개선합니다.

📊 Impact: API 요청 대기 시간이 병렬로 처리되므로, 실행 시간이 크게 단축될 것으로 예상됩니다.

🔬 Measurement: 스크립트 실행 시 로그 및 완료 시간 확인.

👋 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!

Before / after behavior

• observed — Modified behavior in plan.md: current_head_run_coalescer.py의 두 조회 작업을 각각 최대 5개 작업자로 병렬화하는 계획과 Ruff 검사, 테스트·린터 실행, 한국어 PR 제출 절차를 문서에 추가했습니다. 이는 계획 문서의 변경이며 해당 코드 동작 자체의 변경을 나타내지는 않습니다.
• observed — Modified behavior in scripts/ci/current_head_run_coalescer.py: concurrent.futures와 functools 가져오기를 추가했습니다.
• observed — Modified behavior in scripts/ci/current_head_run_coalescer.py: 연결된 비현재 PR 번호가 1개 이하이면 기존처럼 순차 조회합니다. 2개 이상이면 최대 5개 작업자로 _fetch_pr 요청을 병렬 실행하고 결과를 번호별로 구성합니다. 스레드 풀은 finally에서 대기 없이 종료 요청을 받습니다.
• observed — Modified behavior in scripts/ci/current_head_run_coalescer.py: 형제 실행 ID가 1개 이하이면 기존처럼 순차 조회합니다. 2개 이상이면 최대 5개 작업자로 _fetch_run 요청을 병렬 실행하고 결과를 반환합니다. 스레드 풀은 finally에서 대기 없이 종료 요청을 받습니다.

mismatched lengths between sorted(numbers) and results raise an error.
- Around line 426-432: Add tests that exercise the multi-item lookup paths used
by `_associated_prs` and `_refresh_siblings`: provide two PRs or sibling runs,
then verify every result is associated with the correct PR number or run ID and
that each expected lookup occurs. Preserve the existing single-item coverage.
