### Expected behavior

When the new version is released, I'm assuming the feeds with updates are reflected within 2hrs

### Additional context

It is impossible to update frequently from winget feeds, as it seems.
I'm going to try manual download and install from github.com.

Start by reproducing `copilot update` and prompt `/update` in Windows PowerShell 7.5.5 with GitHub Copilot CLI 1.0.20, noting the `TypeError: terminated` and ENOENT rename errors under `.copilot\pkg\universal`. Done means the command can obtain and install a newer version without those failures.
