Phase 7c: 분류기 fallback 키워드 분류 + Haiku 도구 제약 + tier 재분배

- Qwen Classify v2 catch: GPU 실패 시 키워드 정규식으로 intent 추정
  (calendar/note/mail/log_event 도구 호출 경로 보존)
- Call Haiku: [기능 범위] 섹션 항상 추가 — 거짓 응답 방지
- 분류기 프롬프트: response_tier local 범위 확대 (단순 질문, mail 간단조회)
- No RAG Context / Build RAG Context: api_light→local 전환기 오버라이드
- Log Classification: fallback_method 필드 추가
- GPU 헬스체크 스크립트 + LaunchAgent 추가
