Subject: [PATCH] fix: add missing @classmethod decorator to
 load_model_tokenizer

The load_model_tokenizer method in HuggingFaceModelMixin was missing the
@classmethod decorator, causing a TypeError when called on the class.
Without it, 'cls' receives the first positional argument (model_name)
instead of the class, making the method uncallable as intended.
