Add pipeline_tag, library_name, and direct paper link

This PR enhances the model card for `MedVLSynther-3B-RL_10K` by adding key metadata and improving content discoverability:

* **`pipeline_tag: image-text-to-text`**: This categorizes the model for multimodal visual question answering, ensuring it appears under the correct pipeline filter on the Hugging Face Hub.
* **`library_name: transformers`**: Evidence from the `Usage` section and `config.json` confirms compatibility with the 🤗 Transformers library, enabling the automated "how to use" widget on the model page.
* **Direct Paper Link**: A direct link to the paper on the Hugging Face Hub (`https://huggingface.co/papers/2510.25867`) has been added at the top of the model card for easier access to the research.

These updates improve the model's discoverability and user experience on the Hub.
