chore(scripts): rename script API to GetComponent/TryGetComponent; misc

Clearer accessor naming on ScriptBehavior (Get -> GetComponent,
TryGet -> TryGetComponent), WASDMove follows. Teleport marked const
(JPH Ref does not propagate constness). Spinner: auto-rotation
disabled for the moment, registration switched from the registration
macro to an explicit lambda to verify the mechanism.
