Phase 5-6: API usage tracking + Calendar/Mail/DEVONthink/OmniFocus/News pipeline

- 파이프라인 42→51노드 확장 (calendar/mail/note 핸들러 추가)
- 네이티브 서비스 6개: heic_converter(:8090), chat_bridge(:8091),
  caldav_bridge(:8092), devonthink_bridge(:8093), inbox_processor, news_digest
- 분류기 v2→v3: calendar, reminder, mail, note intent 추가
- Mail Processing Pipeline (7노드, IMAP 폴링)
- LaunchAgent plist 6개 + manage_services.sh
- migrate-v3.sql: news_digest_log + calendar_events 확장
- 개발 문서 현행화 (CLAUDE.md, QUICK_REFERENCE.md, docs/architecture.md)
