## Checklist

- [ ] I kept this pull request focused and avoided unrelated refactors.
- [ ] I followed the Electron layer boundary: Renderer → Preload/Bridge
→ Main.
- [ ] I validated IPC input at the boundary when applicable.
- [ ] I avoided `any`, `@ts-ignore`, and unnecessary `@ts-expect-error`.
- [ ] I updated Simplified Chinese locale files for new or changed
user-visible UI text.
- [ ] I updated documentation when behavior, setup, or user-facing
functionality changed.
- [ ] I considered privacy, security, and user-data impact.
