 * 光湖自主开发Agent（GuangHu Lake Autonomous Dev Agent）
 *
 * 功能：
 *   - PM2 常驻服务，24小时运行
 *   - 监听任务队列，自动执行开发任务
 *   - 提供 HTTP API 查询状态
 *   - 支持命令行操作（status / run / submit）
 *
 * 用法：
 *   node glada/service.js              启动 GLADA 服务
 *   node glada/service.js --status     查看系统状态
 *   node glada/service.js --run-once   只执行一个任务就退出
 *   node glada/service.js --submit     提交新任务（JSON 从 stdin）
 *
 * PM2:
 *   pm2 start glada/ecosystem.config.js
