This PR improves the model card for Orion-MSP by:
- Adding `pipeline_tag: other` to help users discover this tabular in-context learning model on the Hugging Face Hub.
- Including `library_name: scikit-learn` as the model provides a scikit-learn compatible interface, enabling an automated usage snippet.
- Adding a prominent link to the Hugging Face paper page [Orion-MSP: Multi-Scale Sparse Attention for Tabular In-Context Learning](https://huggingface.co/papers/2511.02818) in the introductory section.
These updates will enhance the model's visibility and usability for the community.
