perf(prisma): index relation lookup by source field - #1081
Conversation
`exportPrisma` 함수 내부의 컬럼 루프 안에 있던 모든 엣지 순회 로직(O(E))을 미리 계산된 O(1) Map 참조 방식으로 대체했습니다. 대규모 다이어그램 내보내기 시 O(N * C * E)의 심각한 성능 병목 현상을 해결합니다.

This branch builds a source-model/source-field lookup once and performs direct lookup inside the column loop. That is a valid structural reduction in repeated edge scans; the existing behavior tests remain the compatibility boundary.It is not yet buyer-performance evidence. The branch contains no reproducible workload benchmark fixing node/column/edge distributions, browser or JS runtime, warm-up/repetition protocol, allocation/GC evidence, or end-to-end Prisma-export latency. Therefore wording that large models become materially or dramatically faster is not accepted as measured fact, and this PR remains Draft.
