In `@src/main/java/com/mr/domain/mentor/service/MentorSseConnectionManager.java`:
- Around line 39-41: MentorSseConnectionManager의 open, sendStart, sendChunk,
complete 흐름을 동일 sessionId별 잠금으로 직렬화하여 연결 교체·이전 연결 종료·이벤트 전송·완료 처리가 세션 전환과 경쟁하지
않도록 수정하세요. 모든 전송 및 완료 경로에서 잠금 획득 후 ensureActive를 확인해 stale 연결이 새 generation 활성화
이후 동작하지 않게 하고, 기존 generation 검증 동작은 유지하세요. 동일한 경쟁을 재현하는 latch 기반 테스트를 추가하세요.

activeConnections.remove(sessionId, connection)을 사용한 방식이 적절한지questionService.fail()을 호출하지 않아 현재 generation 상태를 침범하지 않는지questionService.complete()와 연결 종료 상태 전이를 동일한 connection lock 안에서 처리하여 저장과 supersede 경합을 방지한 부분이 적절한지✅ 체크리스트
