admin config gateway — edit the profile’s gateway section: enable state,
routing patterns, and the default provider.
Every mutation resolves the resulting spec and validates it against the
profile’s provider registry (profile.providers), so a route or
default-provider that names a provider absent from the registry fails at the
edit rather than at the next boot. The gateway owns no catalog: providers
and models live in profile.providers (see admin config catalog).
