feat(v029): NoteRepository.setStatus + listByStatus + restoreNote 재구현

- NoteStatus 타입 추가 ('active'/'completed'/'archived'/'trashed')
- Note interface 에 status / statusChangedAt / moveReason 필드 추가
- setStatus(id, status, reason, now?) — 단일 transaction 으로 status + move_reason +
  status_changed_at + updated_at 갱신. status='trashed' ↔ deleted_at 동기화
  (backward compat). 그 외 status 는 deleted_at NULL.
- listByStatus(status, opts) — status 별 필터 + ORDER BY COALESCE(status_changed_at,
  created_at) DESC. limit cap 200.
- hydrate 에 status / statusChangedAt / moveReason 매핑 추가. 미설정 row 는 'active' fallback.
- restoreNote 재구현 — setStatus('active', null) 로 status + deleted_at 동기화 +
  v0.2.6 #10 round 1 fix (ai_status='failed'/'pending' → pending_jobs 재투입) 보존.
- 기존 테스트 fixture 5건에 새 필드 추가 (NoteCard, store.expired/recall/tagFilter/trash).
- 신규 테스트 11건 (setStatus + listByStatus + restoreNote 회귀).
