[Feature]: 通过镜像安装 QwenPaw，使用 codex cli 等第三方 agent时如果镜像更新 code cli 和配置都没了。。。

## Summary

通过镜像安装 QwenPaw，codex cli 等第三方 agent 需要在镜像中安装， 如果镜像更新 code cli 和配置都没了。。。
推荐在QwenPaw镜像中预装codex cli？或者提供一键安装codex功能？

The issue names no files, tests, or entry points. Inspect the image installation and update flow, then trace how third-party agent CLIs and their configuration are handled; compare preinstallation with a one-click installation path. Done means the requested Codex CLI workflow is available and its configuration is not lost after an image update.
