Add model card and metadata for FIRM

Hi! I'm Niels from the Hugging Face community team. I've updated the model card to include relevant metadata such as the library name, pipeline tag, and links to the paper, project page, and code repository. This will make the model more discoverable and easier to use within the Hugging Face ecosystem.

+This repository contains the weights for the model presented in the paper [Trust Your Critic: Robust Reward Modeling and Reinforcement Learning for Faithful Image Editing and Generation](https://huggingface.co/papers/2603.12247).

+
+## Introduction
+
+FIRM (Faithful Image Reward Modeling) is a comprehensive framework that develops robust reward models to provide accurate and reliable guidance for faithful image generation and editing. It addresses the common issue of reward models suffering from hallucinations and noisy scores during reinforcement learning (RL). 
+
+This model, **FIRM-Qwen-Edit**, is an image editing model trained using the FIRM framework. It leverages a novel "Base-and-Bonus" reward strategy called Consistency-Modulated Execution (CME) to balance the competing objectives of instruction following and visual consistency.
+
+## Repository Layout
+
+The official implementation in the GitHub repository is organized as follows:
+- `generation/`: GenerationRL training and reward serving.
+- `editing/`: EditRL training, reward serving, and reproduction scripts.
