Research direction

Start by reviewing the referenced Hugging Face Transformers pull request 27539 to understand the intended 4D attention-mask behavior. Then trace how CTranslate2 handles attention masks for Llama and determine the scope for supporting custom masks in other models. Done means custom 4D masks work correctly for Llama, with any broader support clearly defined.
