"""
Hugging Face Transformers Integration for Q-TensorFormer.

Provides first-class Hugging Face ecosystem compatibility:
  - QTensorFormerConfig (inherits PretrainedConfig)
  - QTensorFormerForCausalLM (inherits PreTrainedModel, GenerationMixin)
  - AutoConfig & AutoModelForCausalLM registration
  - Generation support with past_key_values and Adaptive KV Cache
  - save_pretrained and from_pretrained serialization
