Add pipeline tag, paper link, and project page link

This PR improves the model card by:

* Adding the `pipeline_tag: text-generation` to the metadata, which accurately reflects the model's conversational and reasoning capabilities and improves its discoverability on the Hugging Face Hub (https://huggingface.co/models?pipeline_tag=text-generation).
* Adding a prominent link to the Hugging Face paper page ([Baichuan-M2: Scaling Medical Capability with Large Verifier System](https://huggingface.co/papers/2509.02208)) at the top of the content for easier access to the research paper.
* Adding a prominent link to the technical blog/project page ([Blog - Baichuan-M2](https://www.baichuan-ai.com/blog/baichuan-M2)) at the top of the content for quick access.
* Retaining the existing `library_name: transformers` and `license: apache-2.0` metadata fields.
