⚡ Bolt: [성능 개선] NetworkGraph 이벤트 핸들러의 O(N) 노드 검색을 O(1) Map 검색으로 변경

[seonghobae]

💡 무엇을: NetworkGraph.tsx의 노드 선택 이벤트 핸들러(selectNode, selectGraphNode)에서 노드 라벨을 찾을 때 O(N) 시간 복잡도를 가진 findNodeLabel 대신 이미 계산된 O(1) nodeMap과 객체 프로퍼티를 직접 사용하도록 수정했습니다.
🎯 왜: 데이터 양이 늘어날 경우 이벤트 발생 시 Array.prototype.find() 호출로 인한 성능 병목(O(N))을 방지하기 위함입니다.
📊 영향: 그래프에서 노드 클릭 등 상호작용 시 불필요한 배열 순회를 제거하여 응답성을 개선했습니다.
🔬 측정 방법: 노드가 많은 그래프에서 클릭 이벤트 시의 지연 시간을 확인하여 개선되었는지 측정할 수 있습니다.

Node selection in NetworkGraph.tsx now resolves labels through the precomputed nodeMap or the selected node property. Selection behavior and displayed text remain unchanged.

Changes

Network node selection

Layer / File(s)	Summary
