feat(04-03): PrinterDriver interface, MockDriver, PrtQutieDriver stub
- PrinterDriver interface: Connect/Print(bitmap,w,h)/Disconnect
- ImageToRawBitmap(): 1-bit packed row-major converter from image.Image
- MockDriver: saves PNG to SaveDir (/tmp default) for visual inspection
- PrtQutieDriver: stub returns ErrNoDevice — safe before hardware arrives
- ErrNoDevice, ErrNotConnected, ErrEmptyBitmap sentinel errors
