Add pipeline tag, library name, and Hugging Face paper link

This PR enhances the model card by:
- Adding `pipeline_tag: image-text-to-text` to improve discoverability on the Hugging Face Hub, as the model takes images and text inputs to generate text.
- Adding `library_name: transformers` to enable the automated "how to use" widget, as evidenced by the provided sample usage code snippet leveraging the `transformers` library.
- Including a direct link to the Hugging Face paper page ([https://huggingface.co/papers/2512.15713](https://huggingface.co/papers/2512.15713)) for easy access to the associated research on the Hub.

The existing license and tags remain unchanged. The sample usage section is already present and correctly formatted.
