```bash
# TASK-007A/B/C merged to cline-dev from feature/task-007-integrated-backend
# TASK-007D merged to cline-dev from feature/task-007d-launcher-ui
```

## Testing Notes

The UI components use IPC handlers registered in main.js. To test:

1. Run `npm run dev`
2. Open Backend Services panel
3. Create a local backend (name it)
4. Start/Stop the backend
5. Check the displayed endpoint when running
