BuiltinProviderModule

The META-INF/services entry point for the providers llm4s-core ships.

This is a class rather than an object because java.util.ServiceLoader instantiates the class named in the services file through its public no-arg constructor, and a Scala object exposes its instance as a MODULE$ field instead. The same shape is what GraalVM's ServiceLoaderFeature needs, so a provider module written this way works under native-image too.

It delegates to BuiltinProviders, which stays the readable list.
