实测显示Codex的计算机使用能力比cua-driver好用

这个牛逼，把codex 的computer use 能力赋予给其他harness.

实测在我自己的xharness 里也可以使用codex 的computer use 了，速度和准确率的确要比cua-driver的要好用。

原帖是在claude code里使用codex的computer use, 提示词：
``` "Set up Codex's computer use as an MCP server for you on my Mac. Find the "cua_repl" entry in ~/.codex/plugins/cache/openai-bundled/unified-computer-use/<newest version>/.mcp.json and register it as a user MCP server called "codex-cu" with the same command, args and env. Then test it by using Calculator in the background to work out 12 × 12." ```
