Improve model card: Add pipeline tag, paper link, and GitHub badge

This PR improves the model card for the "Reward Forcing" model by:

* Adding the `pipeline_tag: text-to-video` to the metadata, which enables better discoverability on the Hugging Face Hub (e.g., via `huggingface.co/models?pipeline_tag=text-to-video`).
* Adding a clear introductory link to the paper, [Reward Forcing: Efficient Streaming Video Generation with Rewarded Distribution Matching Distillation](https://huggingface.co/papers/2512.04678), at the top of the model card content.
* Adding a dedicated GitHub badge to the header for easier access to the associated code repository.

The existing content, including the inference code snippets, remains unchanged.
