- Delete modules/master_machine/ (old seasky protocol vision module)
- Rename modules/opencv/ → modules/master_machine/
- Rename opencv.h/c → master_machine.h/c
- Remove master_process.h include from robot_def.h and ins_task.c
- Remove VisionSetAltitude() call from ins_task.c (send not needed)
- Update all #include paths and CMakeLists.txt
