Replaces Orin↔ESP32-S3 BALANCE CAN comms (0x300-0x303 / 0x400-0x401)
with binary serial framing over CH343 USB-CDC at 460800 baud.
Protocol matches bd-wim1 (sl-perception) exactly:
Frame: [0xAA][LEN][TYPE][PAYLOAD][CRC8-SMBUS]
CRC covers LEN+TYPE+PAYLOAD, big-endian multi-byte fields.
Commands (Orin→ESP32): HEARTBEAT/DRIVE/ESTOP/ARM/PID
Telemetry (ESP32→Orin): TELEM_STATUS, TELEM_VESC_LEFT (ID 56),
TELEM_VESC_RIGHT (ID 68), ACK/NACK
VESC CAN TWAI kept for motor control; drive commands from Orin
forwarded to VESCs via SET_RPM. Hardware note: SN65HVD230
rewired from IO43/44 to IO2/IO1 to free IO43/44 for CH343.
