This PR enhances the model card by:
- Adding the `pipeline_tag: image-text-to-text` to better categorize the model's functionality (processing images and text to generate text) and improve discoverability on the Hugging Face Hub.
- Specifying `library_name: transformers` to enable direct usage via the Hugging Face `transformers` library and showcase an automated "how to use" widget on the model page.
- Updating the paper link to point to the official Hugging Face Papers page: [Mobile-Agent-v3: Foundamental Agents for GUI Automation](https://huggingface.co/papers/2508.15144).
- Adding a link to the project page: `https://osatlas.github.io/` for more context.
These changes will improve the model's discoverability and usability on the Hugging Face Hub.
