+offer to run `gh auth login` interactively to set up authentication.

+- `results`: AutotuneResults object from autotune_setup
+- `auto_login`: If true, prompts to authenticate if not already authenticated (default: true)

+## Automatic (New!)
+If gh is not authenticated, the function will offer to run authentication for you.
