Improve model card: Add pipeline_tag and HF paper link

This PR enhances the model card by:
- Moving `robotics` from the `tags` list to `pipeline_tag: robotics` in the metadata to improve discoverability on the Hugging Face Hub.
- Adding a prominent link to the Hugging Face paper page: [InternVLA-M1: A Spatially Guided Vision-Language-Action Framework for Generalist Robot Policy](https://huggingface.co/papers/2510.13778) at the top of the model card.

Please review and merge if these improvements align with your goals.
