- app_header_init: detect vehicle(class=2) in print_yolo_result(),
send CAN speed=10 on detection, speed=240 on clear;
only triggers on state change, keepalive maintains cmd
- app_header_init: on speed state change, send BLE JSON
{response_type:can_status, content:{vehicle_detected, speed_cmd}}
- app_header_init: add #include can_bus.h / bt_uart.h
- event_recorder: wrap legacy MsgBroker IPC path in #if 0;
setSpeed now goes directly through can_bus_send_control_cmd()
