👋 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.

📝 Info: Map refactor preserves last-write-wins semantics
The old inner loop over edgesProcessed overwrote relationDef per match, so the last edge in insertion order won. The new edgeRelationsByModelAndField Map overwrites in the same edge order, keeping the same surviving relation per (model, field). Key building and lookup use identical sanitized values, and sanitizeName strips :, so no collisions arise. The change is behaviorally equivalent.

| **Learning:** Prisma 내보내기 시 모든 노드의 모든 컬럼을 순회하며 `edgesProcessed` 배열을 찾는 과정에서 `O(N * C * E)` 성능 병목이 발생했습니다. | ||

sourceHandle과 targetHandle을 원래 열 이름으로 해석하고 중복 관계를 보존하세요.
convert.ts와 TableNode은 src-c-... 및 tgt-c-... 형식의 핸들을 생성합니다. 이 코드는 접두사만 제거하므로 user_id가 c-...로 해석됩니다. 그 결과 관계 조회 키가 실제 열 키와 일치하지 않고, references에도 잘못된 열 이름이 사용됩니다. 핸들과 실제 열 이름을 일치시키는 로직을 사용하세요.
동일한 모델·필드에 여러 edges가 있으면 Map.set이 마지막 targetModel, targetField, relationName만 보존합니다. 입력이 이를 허용하면 관계 배열을 저장해 모두 생성하거나 중복을 명시적으로 거부하세요. 인코딩된 핸들과 중복 키에 대한 회귀 테스트도 추가하세요.

💡 What: Prisma 내보내기 시 엣지(관계) 조회를 최적화하기 위해, 모든 노드의 모든 컬럼을 순회하며
edgesProcessed배열을 찾는 대신 모델과 필드를 키로 하는 Map을 미리 계산하여 사용합니다.🎯 Why:
frontend/src/erd/prisma.ts에서 관계를 결정할 때O(N * C * E)의 중첩 루프가 발생했습니다. 대규모 스키마의 경우 컬럼 루프 내부에서edgesProcessed를 반복 조회하는 것은 성능 병목과 과도한 오버헤드를 유발합니다.📊 Impact: 엣지 관계 구축의 시간 복잡도를
O(N * C * E)에서O(1)Map 조회를 통한O(N * C)로 감소시켜 내보내기 성능을 크게 향상시킵니다.🔬 Measurement: 대규모 스키마(예: 노드 50개, 엣지 100개 이상)를 Prisma로 내보낼 때 정상 작동 및 처리 속도가 향상되었는지 확인합니다.
