feat: 이드 기능 완성 — note_bridge, intent_service, CalDAV Todo

- note_bridge.py: port 8096, log-conversation 제거, message 필드 추가
- intent_service.py: 의도 분류(Ollama→Claude fallback) + 한국어 날짜 파싱 + API 사용량 추적
- caldav_bridge.py: VTODO 생성 (/calendar/create-todo) + 응답 message 필드
- LaunchAgent plist: note-bridge (8096), intent-service (8097)
- .env.example: API_MONTHLY_LIMIT, NOTE_BRIDGE_URL, INTENT_SERVICE_URL
