feat: implement asynchronous action call system

- Add async callback support with proper argument passing
- Implement remote action invocation via TCP connection
- Add hello_world_action example demonstrating async communication
- Improve ActionPool with type-safe async processing
- Update client registry for remote action handling
- Enhance ActionContext with better instance management
- Support both local and remote action execution modes
