    For scene actors, targets root component unless component_name given.
    For blueprints, component_name is required. preset_name must be a
    registered profile (built-ins: BlockAll, OverlapAll, Trigger, NoCollision,
    Pawn, PhysicsActor, etc.) — unknown names silently fall back to NoCollision.
    Only PrimitiveComponents accepted.

    Example: `set_collision_preset("BlockAll", actor_name="MyCube")`
