Add pipeline tag, paper link, and project page metadata

This PR enhances the `Kwaipilot/KAT-Dev` model card by:
- Adding the `pipeline_tag: text-generation` to the metadata for better discoverability of this large language model.
- Adding the `project_page: https://kwaipilot.github.io/KAT-Coder/` to the metadata, linking to the existing project blog for comprehensive details.
- Including a direct link to the associated paper, [KAT-Coder Technical Report](https://huggingface.co/papers/2510.18779), at the beginning of the model card content for clear attribution.

These updates aim to provide users with more complete and easily accessible information about the model.
