feat: Implement JSON-based type-erased action invocation

- Add process_json method to ActionPool for type-agnostic calls using JSON serialization
- Extend ActionContext with action_name and action_args fields and setter methods
- Update action_gen macro to use process_json instead of typed process method
- Implement remote action invocation framework in client_registry and action_service
- Add protocol definitions for remote action communication
- Enable flexible action execution without explicit type specifications
