Error: Native addon "runtime" not found for win32-arm64

### Describe the bug

I updated Copilot CLI (running on Windows, arm64 architecture), and started getting this error every time I interact with it:

`Error: Native addon "runtime" not found for win32-arm64`

I have it installed through winget. Repeated attempts to uninstall / reinstall does not resolve it. Restarting my PC does not resolve it. When I force winget to use the x64 version of Copilot instead, it works though.

### Affected version

v1.0.48-0

### Steps to reproduce the behavior

1. Run `winget install GitHub.Copilot --architecture arm64`
2. Run `copilot`
3. Type anything in the console
4. Copilot responds with the error message above.
Note: if I switch the install command above to architecture x64, Copilot still works, so it seems to be an arm64 issue.

### Expected behavior

Copilot should work with arm64-based architectures.

### Additional context

_No response_

先使用 `winget install GitHub.Copilot --architecture arm64` 重現失敗，然後在 Windows arm64 系統上執行 `copilot`，並與 x64 安裝進行比較。追蹤 `runtime` addon 的原生 addon 載入路徑；當 arm64 安裝能夠啟動並回應，且不出現找不到錯誤時，即表示完成。
