```

refactor(server): 更新服务器配置和部署脚本- 更改默认端口为3350，以适应生产环境。
- 增加了API信息端点，提供更详细的API状态信息。
- 提高了速率限制，以适应生产环境的更高请求量。
- 添加了错误处理中间件和404处理，增强了错误处理能力。
- 添加了优雅关机处理，确保服务器在接收到SIGINT或SIGTERM信号时能够优雅关闭。- 创建了生产环境配置文件示例 `.env.production.example`，并提供了详细的部署指南 `DEPLOYMENT_GUIDE.md`。
- 添加了启动脚本 `start-server.sh` 和同步脚本 `sync-to-server.sh`，简化了部署流程。
- 配置了Nginx配置文件 `xlxumu-api.conf`，支持HTTPS和反向代理。
