Improve model card and metadata

Hi! I'm Niels from the Hugging Face community team.

This pull request improves the model card for RA-Monitor by:
- Adding the `image-text-to-text` pipeline tag for better discoverability.
- Specifying `library_name: transformers` based on the model configuration.
- Including a description of the M3-AD framework and RA-Monitor mechanism.
- Providing links to the research paper and official GitHub repository.

These changes help users understand the model's purpose and how to cite the work.

+# M3-AD: RA-Monitor
+
+This repository contains the model weights for **RA-Monitor**, a unified reflection-aware multimodal framework for industrial anomaly detection. RA-Monitor is part of the M3-AD framework presented in the paper [M3-AD: Reflection-aware Multi-modal, Multi-category, and Multi-dimensional Benchmark and Framework for Industrial Anomaly Detection](https://huggingface.co/papers/2603.00055).
+
+## Model Description
+RA-Monitor addresses the issue where multimodal large language models (MLLMs) produce high-confidence but unreliable decisions in complex industrial scenarios. It introduces a reflection-aware mechanism that models reflection as a learnable decision revision process. This allows the model to perform controlled self-correction when initial judgments are unreliable, significantly improving anomaly type recognition and spatial localization.
+
+The framework is built upon:
+- **RA-Monitor**: A mechanism that equips pre-trained models with thinking and reflective abilities.
+- **M3-AD-FT**: A dataset designed for reflection-aligned fine-tuning.
+- **M3-AD-Bench**: A benchmark for systematic cross-category evaluation of industrial anomaly detection.
