Subject: [PATCH] feat(quickcapture): React UI with v0.2 recovery-friendly copy
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Task 19 of the slice plan. Frameless dark card with:
- placeholder "지금 머릿속에 있는 것 한 줄. 정리는 나중입니다."
- hint "Ctrl+Enter 구출 · Esc 취소 · 이미지 붙여넣기"
- Ctrl/Cmd+Enter to submit (window.inkling.capture.submit then
  hide), Esc to cancel (with "이 한 줄을 흘려보낼까요?" confirm
  when text > 5 chars)
- clipboard image paste -> thumbnail strip with ArrayBuffer
  retained for submit
- fallback "저장에 실패했습니다. 다시 시도해주세요." in-card on
  IPC error (window stays open with content preserved)

api.ts wraps window.inkling.capture as the typed CaptureApi.
main.tsx mounts <App /> on #root.
