 当 `container.enable = true` 且 `addToSystemPackages = true` 时，主机上的**所有** `hermes` 命令都会自动路由到托管容器中执行。这意味着你的交互式 CLI 会话在与 gateway 服务相同的环境中运行——可以访问所有容器内安装的包和工具。
 
-- 路由是透明的：`hermes chat`、`hermes sessions list`、`hermes version` 等命令都会在底层 exec 进容器
+- 路由是透明的：`hermes chat`、`hermes sessions list`、`hermes --version` 等命令都会在底层 exec 进容器
 - 所有 CLI 参数原样转发
 - 如果容器未运行，CLI 会短暂重试（交互式使用时显示 5 秒 spinner，脚本中静默等待 10 秒），然后以明确的错误退出——不会静默回退
 - 对于在 hermes 代码库上工作的开发者，设置 `HERMES_DEV=1` 可绕过容器路由，直接运行本地检出版本
