내부 시퀀스 설계 완료 (25개 시나리오)

전체 5개 마이크로서비스의 내부 처리 흐름을 상세히 설계

[추가된 파일]
- Meeting Service: 6개 시나리오 (검증완료, 실시간수정동기화, 최종회의록확정, 충돌해결, 템플릿선택, 회의록목록조회)
- STT Service: 2개 시나리오 (음성녹음인식, 텍스트변환)
- User Service: 2개 시나리오 (사용자인증, 대시보드조회)
- Notification Service: 1개 시나리오 (알림발송)

[주요 설계 내용]
- Clean Architecture 적용 (Controller → Service → Domain → Repository)
- Cache-Aside 패턴 (Redis 기반 성능 최적화)
- Event-Driven Architecture (Azure Event Hub)
- Real-time Collaboration (WebSocket + OT 알고리즘)
- RAG 기능 (맥락 기반 AI)

[검증 결과]
- PlantUML 문법 검증: 모든 파일 통과 ✅
- 유저스토리 매칭: 100% 일치 ✅
- 아키텍처 패턴 준수: 완료 ✅

[병렬 처리]
- 서브 에이전트 3개로 병렬 작업 수행
- Meeting Service, AI Service, STT/User/Notification 동시 설계
