fix: Claude CI ワークフローの cancel-in-progress を無効化

[keito4]

概要

• Claude Code CI ワークフローの cancel-in-progress を true → false に変更

背景

同じ Issue/PR に対して新しい @claude リクエストが来た際に、cancel-in-progress: true により実行中のジョブがキャンセルされ、処理が完了しない問題が頻発していた。

変更後の動作

• 実行中のジョブは最後まで完了する
• 新しいリクエストはキューで順番待ちになる

Now runs to completion, no trick,

🔍 AI Code Review (Local Hook)

Models: Codex (default) / Gemini (default)

🤖 Codex Review

指摘事項:

1. 並行実行のキャンセル無効化により、同一Issue/PRに対するワークフローが重複実行され、重複コメントやレース（同じ権限での書き込み衝突）、実行枠消費やレート制限超過が発生しやすくなります。意図がないなら cancel-in-progress: true を維持するか、重複実行を許容する理由と回避策を併記すべきです。.github/workflows/claude.yml:13-15

判定: patch is incorrect
理由: 重要なワークフローの並行制御を弱める変更で、実害（重複実行・衝突・コスト/レート制限）の可能性が高い。
信頼度: 0.56

指摘事項

1. 競合実行の抑止が無効化されています。cancel-in-progress: false により同一グループのジョブが並行実行され、同一Issue/PRに対する重複コメントや無駄なランナー消費、前後関係の乱れが発生する可能性があります。意図的でない限り、CIコストとノイズ増大につながります。影響箇所: .github/workflows/claude.yml:12-16

判定: patch is incorrect
理由: 既存の並行実行抑止が解除され、運用上のリスク（重複実行・コスト増・競合コメント）を導入しているため。

13-15: 変更は妥当ですが、キューの管理に注意が必要です。

The change correctly addresses the issue where running Claude jobs were being cancelled. Setting cancel-in-progress: false ensures that each @claude request completes.

However, be aware of operational implications:

• Queue buildup: Multiple rapid @claude mentions on the same issue/PR will queue sequentially. With a 20-minute timeout per job (line 32), 5 requests could take up to 100 minutes to complete.
• Resource consumption: All queued jobs will consume GitHub Actions minutes, even if later requests supersede earlier ones.
• Stale operations: Jobs later in the queue might work with outdated context if the issue/PR changes during earlier job execution.

Consider monitoring:

• Average queue depth per issue/PR
• Failed jobs due to stale context
• Total Actions minutes consumed

If queue buildup becomes problematic, potential mitigations include:

• Reducing timeout-minutes to fail faster
• Implementing a debounce mechanism
• Using a time-based concurrency group (e.g., include timestamp rounded to nearest 5 minutes)

duplicate `@claude` triggers before enqueueing, or change the concurrency group
key to a time-bucketed value (e.g., include a rounded timestamp) so jobs batch;
also add simple metrics/logging for queue depth, failed stale jobs, and Actions
minutes consumed to monitor impact.
