## Summary by CodeRabbit

- **New Features**

- **Refactor**
  - Streamlined server build, startup, and artifact management processes.
  - Reorganized and simplified workflow and configuration files for backend services.
  - Transitioned export styles and import mechanisms for native modules to enhance maintainability.

- **Chores**
