This PR improves the model card by:
- Adding `library_name: transformers` to the metadata to enable the "Use in Transformers" button.
- Adding `pipeline_tag: text-generation` for better categorization.
- Linking the model to its associated research paper: [FineInstructions: Scaling Synthetic Instructions to Pre-Training Scale](https://huggingface.co/papers/2601.22146).
