Add pipeline_tag, library_name, and paper link to metadata

This PR enhances the model card by adding key metadata tags:
- `pipeline_tag: text-generation`: This correctly categorizes the model, ensuring it appears in relevant searches and filters on the Hugging Face Hub (e.g., https://huggingface.co/models?pipeline_tag=text-generation).
- `library_name: transformers`: This indicates that the model can be easily loaded and used with the Hugging Face Transformers library, enabling the "Use in Transformers" widget on the model page for improved usability.
- `paper: 2507.09104`: This links the model directly to its official Hugging Face paper page, enhancing discoverability and providing immediate access to the research context.

The existing content of the model card is preserved as it already provides comprehensive information.
