👋 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.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Add a regression test for the memoization behavior.
This cohort changes production code without adding or updating a test. The supplied frontend/src/components/NetworkGraph.test.tsx:63-71 path covers mounting and initialization, but not unrelated parent updates. Add a test that verifies a parent state update does not construct another vis-network instance.
As per coding guidelines, TDD is expected: add or update tests before production code changes.

💡 무엇을: 무거운 타사 DOM 조작 라이브러리(vis-network)를 초기화하는
NetworkGraph컴포넌트를React.memo로 감싸고 변경 이유를 설명하는 주석을 추가했습니다.🎯 왜:
NetworkGraph컴포넌트는 무거운 서드파티 DOM 라이브러리를 사용하기 때문에 재초기화 비용이 매우 높습니다. 이를 메모이제이션하지 않으면 대시보드나 레이아웃과 같은 부모 컴포넌트에서 발생하는 빈번하고 관련 없는 상태 업데이트(예: 레이아웃 상태 변경 또는 폴링)로 인해 그래프 전체가 다시 생성되어 심각한 레이아웃 스래싱과 성능 병목 현상이 발생하기 때문입니다.📊 영향: 대시보드 등 부모 컴포넌트 상태 변경 시 발생하는
NetworkGraph컴포넌트의 불필요한 리렌더링 및 재생성(re-instantiation)을 약 100% 감소시킬 것으로 예상됩니다.🔬 측정 방법: React Developer Tools의 Profiler를 사용하여
WorkspaceHome부모 컴포넌트에서 상태 업데이트(예: 일정 변경, 다른 탭 클릭)가 발생할 때NetworkGraph컴포넌트가 리렌더링되는지 확인합니다. 수정 전에는 매번 리렌더링되었으나, 수정 후에는 리렌더링되지 않아야 합니다.PR created automatically by Jules for task 4156872411704475612 started by @seonghobae
