Update metadata and paper link for LongCat-Flash-Omni

This PR improves the model card for the LongCat-Flash-Omni model by:
- Updating the `library_name` to `transformers` to reflect its compatibility with the 🤗 Transformers library, enabling automated code snippets.
- Changing the `pipeline_tag` from `text-generation` to `any-to-any` to accurately represent its comprehensive omni-modal capabilities (text, image, video, and audio understanding and generation).
- Updating the paper link to point to the official Hugging Face paper page: https://huggingface.co/papers/2511.00279.

These changes enhance the model's discoverability and provide more accurate metadata for users on the Hugging Face Hub.
