- Swap HUB0/HUB1 addresses; they were the wrong way round.
- Add DIR_* constants for all seven motors, with DIR_RIGHT_TRACK at -1.
- Swap the right arm buttons: Cross raises, Triangle lowers.
- Move struct Frame into the types block - the Arduino prototype
generator needs it declared above the first function definition.
- Pin core 2.0.17 in the header; 3.x will not build Legoino.
- Parse the extended frame (d-pad and analog triggers).
- Drive both hubs across all seven ports, one input per motor.
- Add a per-hub rate limit alongside the per-port one; hub1 has four
motors and the per-port throttle alone floods it.
- DEBUG_MOTORS flag to log which port each command lands on.
