physics: rigid body drive API (force/impulse/torque/velocity)

PhysicsWorld facade methods addressed by entity bits via body records:
AddForce/AddImpulse/AddTorque (dynamic bodies only, auto-wake), Set/
GetLinearVelocity/SetAngularVelocity (dynamic + kinematic). Inspector
RigidBody block gains impulse debug controls for manual response tests.
Transient by design — nothing serialized.
