PLAUD 수준의 기능 확장:
- 전사 편집: 인라인 편집 + 원본 보존 + 수정됨 표시(점선 밑줄)
- 다중 문서 생성: 회의록/보고서/아이디어노트/커스텀 템플릿
- MD 에디터: 렌더링/편집 토글 (react-markdown + remark-gfm)
- 상세 페이지 리디자인: 풀스크린 탭 전환 구조
- 내보내기: MD, PDF, TXT, DOCX 4종 (docx 패키지)
- 커스텀 프롬프트 템플릿 저장/재사용 (electron-store)
- SSOT: 마크다운 파싱 유틸 추출, 후처리에서 자동 문서 생성 제거

DB: meeting_documents 테이블 + edited_transcript 컬럼
IPC: 8+4 채널, 서비스 2개(MeetingModeService 확장 + MeetingDocTemplateService 신규)
UI: 8개 신규 컴포넌트 (meeting/ 디렉토리), 12개 locale i18n
