The single canonical no-movement profile for MOVEMENT_MEDIUM.NONE
— a disabled profile with zero speeds representing an actor that cannot move
at all (e.g. a Structure).
Actors never author a NONE entry in their SohlActorData.movementProfiles;
this shared constant stands in for it, so every non-mover need not define its
own. It also doubles as the fallback when an actor's currentMoveMedium names
no configured profile (movement in a medium the actor lacks).
