- Move hardware/firmware/ui_freenove_allinone → hardware/ui_freenove_allinone
- All UI hardware now at hardware/ root level
- Single coherent hardware structure complete
Structure now:
- hardware/firmware/ ← Code source
- hardware/ui_freenove_allinone/ ← UI at root level
- hardware/projects/ ← Secondary projects
- hardware/shared/libs/ ← Shared libraries
- hardware/{bom,enclosure,wiring}/ ← Reference docs
