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，在命令提示字元中輸入 `copilot`，使用 GitHub Copilot CLI 1.0.73 重現此問題，並觀察新工作階段期間閃爍的藍色圓圈和載入文字。追蹤啟動載入路徑，並確認一般工作階段不再顯示無限載入，同時保留其預期行為。
