👋 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 New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

📝 Info: Int32Array cache preserves duration values
calculateDurationDays (app.js:1486) returns only non-negative integers, so storing them in Int32Array loses no precision. Both loops index state.tasks by the same i, keeping durationCache[i] aligned with the task. This is more robust than the old id-keyed Map, which could collide on duplicate task ids.

💡 무엇을
computeTaskMetrics함수 내부에서 사용되던Array.prototype.reduce,Array.prototype.forEach및Map캐싱을 일반for루프와Int32Array로 교체했습니다.byTask맵은 타입 계약상.get()메서드를 요구하므로 객체 대신 기존Map을 유지하되, 전체적인 순회 방식을 고전적인 루프로 변경했습니다.🎯 왜
reduce,forEach)는 루프 순회 시마다 콜백 함수 할당과 가비지 컬렉션(GC) 오버헤드를 발생시킵니다.computeTaskMetrics가 반복 호출되어 성능 병목을 유발할 수 있습니다.📊 영향
computeTaskMetrics함수의 실행 속도와 브라우저 메모리 안정성이 개선됩니다.🔬 측정
