用法:
  install-datamanagementd.sh [--binary <datamanagementd二进制路径>] [--source <仓库路径>]

参数:
  --binary  指定已构建的 datamanagementd 二进制路径
  --source  指定 sub2api 仓库路径（脚本会执行 go build）
  -h, --help 显示帮助

示例:
  sudo ./install-datamanagementd.sh --binary ./datamanagement/datamanagementd
  sudo ./install-datamanagementd.sh --source /opt/sub2api-src

下一步建议：
1. 查看日志：sudo journalctl -u sub2api-datamanagementd -f
2. 在 sub2api（容器部署时）挂载 socket:
   /tmp/sub2api-datamanagement.sock:/tmp/sub2api-datamanagement.sock
3. 进入管理后台“数据管理”页面确认 agent=enabled
