chore(release): v0.3.8 — UX hole 일괄 hotfix 8건

전수 audit 후 핵심 root fix 3 + edge cases 5:

ROOT
- inbox:set-status IPC 가 pushNoteUpdated emit (이전엔 stale → 호출처별 refreshMeta 필요)
- upsertNote 가 current view status 인식 (이전엔 잘못된 status 노트 잔류)
- store async 함수 try/catch (이전엔 IPC fail 시 무한 loading)

EDGE
- restoreNote 가 status='active' 도 갱신
- upsertNote trash 판정 deletedAt → status='trashed'
- Modal Escape dismiss 통일 (5개 modal)
- OnboardingWizard IPC fail fallback (try/catch + skip)
- MoveStatusModal overlay 클릭 close
