Add model card and metadata

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

This PR improves the model card by adding relevant metadata and documentation.
- Added `library_name: transformers` as the model configuration indicates compatibility with the library.
- Added `pipeline_tag: text-generation`.
- Added links to the associated research paper and the official GitHub repository for context.
- Included the citation for the project.

+# CoCoReviewBench Model
+
+This repository contains a model checkpoint from the paper [CoCoReviewBench: A Completeness- and Correctness-Oriented Benchmark for AI Reviewers](https://huggingface.co/papers/2605.07905).
+
+## Introduction
+CoCoReviewBench is a benchmark designed for reliable and fine-grained evaluation of AI reviewers. It curates 3,900 papers from ICLR and NeurIPS, focusing on:
+- **Completeness**: Evaluating by category to avoid penalizing models for issues missing in human references.
+- **Correctness**: Filtering human reviews using reviewer-author-meta-reviewer discussions to ensure accuracy.
+
+## Links
