copilot command silently fails on Windows due to getCACertificates('system') error

### Describe the bug

The copilot CLI command silently exits without any output or error message on Windows 11 (on my machine). No error is displayed, making it very difficult to diagnose the issue.

### Affected version

0.0.400

### Steps to reproduce the behavior

1. Install GitHub Copilot CLI: `npm install -g @github/copilot`
2. Run copilot command: `copilot`
3. Command exits immediately with no output

### Expected behavior

The CLI should either:

- Work correctly
- Display a meaningful error message if something fails

### Additional context

**Investigation**
Running the script directly reveals the underlying error:

`node "C:\Users\...\AppData\Roaming\npm\node_modules\@github\copilot\index.js"`

```
node:tls:138
systemCACertificates ||= ObjectFreeze(getSystemCACertificates());
