"""Test that overlay providers with mismatched models.dev keys resolve correctly.

HERMES_OVERLAYS keys may be models.dev IDs (e.g. "github-copilot") while
_PROVIDER_MODELS and config.yaml use Hermes IDs ("copilot").  The slug
resolution in list_authenticated_providers() Section 2 must bridge this gap.
