Evals / RC readiness

Can this drive? — 6644-1

Demo of the RC-car pipeline's first gates on a real 1990s set: functional-role typing, wheel/axle extraction, the RC-readiness checklist, and a kinematic drive (wheels spin at ω = v/r). Rigid-body dynamics — motor torque, mass, traction — is the next gate (G3) and intentionally not faked here.
