Improve model card: Add robotics pipeline tag, links, and description

This PR enhances the model card by:
- Adding the `robotics` pipeline tag for better discoverability on the Hugging Face Hub.
- Confirming the existing `mit` license.
- Linking to the official paper: [Real-to-Sim Robot Policy Evaluation with Gaussian Splatting Simulation of Soft-Body Interactions](https://huggingface.co/papers/2511.04665).
- Providing a direct link to the project page: https://real2sim-eval.github.io/.
- Including a link to the GitHub repository for the code and detailed instructions: https://github.com/kywind/real2sim-eval.
- Adding a concise description of the framework's purpose and key features.
- Including the BibTeX citation for proper attribution.

These additions will make the artifact more informative and discoverable for users.

+# Real-to-Sim Robot Policy Evaluation with Gaussian Splatting Simulation of Soft-Body Interactions
+
+This repository contains the official implementation of the **Real-to-Sim-Policy-Eval** framework, presented in the paper [Real-to-Sim Robot Policy Evaluation with Gaussian Splatting Simulation of Soft-Body Interactions](https://huggingface.co/papers/2511.04665).
+
+This framework introduces a real-to-sim policy evaluation approach that constructs soft-body digital twins from real-world videos. It renders robots, objects, and environments with photorealistic fidelity using 3D Gaussian Splatting. The goal is to provide a reproducible, scalable, and accurate method for evaluating robotic manipulation policies, particularly for tasks involving deformable objects, which are typically challenging and costly to evaluate in the real world.
+
+Key components of the framework include constructing simulation assets, deploying trained PhysTwin for soft-body simulation, policy training via a submodule, and evaluating policies within the constructed simulation environment.
