Description

### Describe the bug

I was unable to run the Github copilot CLI on Oracle Linux 10 when installing though npm. After troubleshooting, I discovered that I am able to run the copilot binary when forcing it to execute via ld directly, but unable when executing the binary normally.

### Affected version

GitHub Copilot CLI 1.0.78

### Steps to reproduce the behavior

1. Run `npm install -g @github/copilot
2. Run `copilot`

### Expected behavior

Copilot launches normally

### Additional context

### Versions
OS: Oracle Linux 10.2
Architecture: x86_64
Node version: v26.6.0
npm version: 12.0.2
Package version: 1.0.78

Research direction

Start by reproducing the failure with `copilot` and inspect the `./copilot` executable using the provided `strace` and `readelf` commands on Oracle Linux 10. Compare how the installed artifact is packaged and launched across supported environments; done means the installed `copilot` command launches normally without invoking `ld.so` directly.
