This PR significantly enhances the dataset card for the COSMOS dataset by:
- Adding `task_categories: ['text-generation']`, `language: ['en']`, and specific `tags` (story-generation, question-generation, summarization, detoxification) to the metadata for improved discoverability.
- Linking to the associated paper: [Compressed and Smooth Latent Space for Text Diffusion Modeling](https://huggingface.co/papers/2506.21170).
- Providing a link to the official GitHub repository: [https://github.com/MeshchaninovViacheslav/cosmos](https://github.com/MeshchaninovViacheslav/cosmos).
- Including a "Sample Usage" section with a bash code snippet for text generation, taken directly from the project's GitHub README.
These additions make the dataset more informative and user-friendly for researchers and practitioners.
