First 2-pilot test: bot was too hot (1200N cruise) and top-heavy -> launched
off on any nudge. Tamed in-scene: cruiseForce 1200->450, linearDamping 1.5,
angularDamping 6, maxAngularVelocity capped at 3, and lowered centerOfMass to
(0,-0.6,0) so it's bottom-heavy and resists cartwheeling. Added a host-only
debugAutoDriveFull flag on TreadPart to feel two-tread coordination solo.
