### Configure Nixpkgs Input with FlakeHub

Source: https://flakehub.com

Replace standard Nixpkgs inputs with a FlakeHub URL to leverage versioned, reliable Nixpkgs releases.

```nix
{
  inputs.nixpkgs.url = "https://flakehub.com/f/NixOS/nixpkgs/*";

  outputs = { self, nixpkgs }: {
    # Flake outputs
  };
}
```

    runs-on: ubuntu-latest
    permissions:
      id-token: write
      contents: read
    steps:
      - uses: actions/checkout@v6
