Walkthrough

A new system module was added to the registry actors, providing registration for system actor methods across multiple versions. The method registration logic was updated to support the system actor, including macro enhancements for handling empty parameters. The redundant get_actor_type_from_code function was removed in favor of using the ActorRegistry method.
