Add pipeline tag, library name, and paper link to metadata

Hi! I'm Niels, part of the community science team at Hugging Face.

This PR improves the model card by adding:
- `pipeline_tag: text-classification`: This helps users find the model under the correct task category (Reward Modeling is typically classified as text classification on the Hub).
- `library_name: transformers`: Based on the usage example, the model is compatible with the `transformers` library.
- `arxiv: 2601.18731`: This links the model repository to its official paper on the Hugging Face Hub.

Best,
Niels

 # Meta Reward Modeling (MRM)
 
 ## Overview

 MRM represents user-specific rewards as adaptive combinations over shared base reward functions and optimizes this structure through a bi-level meta-learning framework.  
 To improve robustness across heterogeneous users, MRM introduces a **Robust Personalization Objective (RPO)** that emphasizes hard-to-learn users during meta-training.
