eternally loading

### Describe the bug

I have started getting an eternal blinking blue circle and either "Loading:" or "Loading: 1 skill" every time I start a
new CLI copilot session now. copilot seems unable to fix the problem, though it thinks its identified the source
...and it says it may be charging me credits while workng on the fix.

### Affected version

GitHub Copilot CLI 1.0.73.

### Steps to reproduce the behavior

just go to command propmpt and type copilot to start a new session

### Expected behavior

Everything seems to work, but the eternal loading is distracting

### Additional context

_No response_

首先，在命令提示符中输入 `copilot`，使用 GitHub Copilot CLI 1.0.73 重现该问题，并观察新会话期间闪烁的蓝色圆圈和加载文本。跟踪启动加载路径，并验证正常会话不再显示无限加载，同时保留其预期行为。
