Initial commit: AI Photo Organizer (Electron + face-api)

Local-first photo organizer that auto-sorts images by face recognition
and EXIF capture date.

- Electron app with 3-process split: Main (Node) / UI Renderer (React) /
  hidden Inference Renderer (face-api + WebGL)
- Core pipeline: scan -> face match + EXIF -> path build -> atomic move/copy
- Move = copy -> verify -> delete; auto-rename on filename collision
- 1st-registered profile = move, others = copy; unmatched -> [미정]/YYYY/MM
- EXIF date with mtime fallback
- Vitest unit tests (pathBuilder / fileOps / concurrency) all green
- electron-builder config for Windows (nsis) + macOS (dmg)
- Docs: PRD / DECISIONS / ARCHITECTURE
