Enhance model card for UniREdit-Bagel: Add metadata, links, and usage

This PR significantly improves the model card for `UniREdit-Bagel` by:
- Adding the `pipeline_tag: image-to-image` to improve discoverability for image editing models.
- Specifying `library_name: transformers` based on evidence in the configuration files, enabling automated usage examples on the Hub.
- Including direct links to the project page and the GitHub repository for easy access to more resources.
- Adding a comprehensive "Introduction" and "Highlights" section derived from the paper abstract and GitHub README.
- Providing a detailed "Sample Usage" section with environment setup, checkpoint preparation, and inference steps, directly copied from the GitHub repository.
- Incorporating relevant images from the GitHub repository to visualize the model's capabilities and the benchmark.
- Adding a correct BibTeX citation for the paper.
- Including contact information.

Please review and merge this PR.

+# UniREdit-Bagel: A Unified Reasoning-based Image Editing Model
+
+This repository hosts **UniREdit-Bagel**, a model developed as part of the research presented in the paper:
+[UniREditBench: A Unified Reasoning-based Image Editing Benchmark](https://arxiv.org/abs/2511.01295)

+
+## Introduction
+We propose **UniREditBench**, a unified benchmark for reasoning-based image editing evaluation with broader evaluation dimension coverage and a robust evaluation pipeline. We also design an automated multi-scenario data synthesis pipeline and construct **UniREdit-Data-100K**, a large-scale synthetic dataset with high-quality chain-of-thought (CoT) reasoning annotations. We fine-tune Bagel on this dataset and develop **UniREdit-Bagel**, demonstrating substantial improvements in both in-domain and out-of-distribution settings.

+</div>
+
+### ✨ Highlights:
+
+-   **Broader Scenario and Reasoning Dimension Coverage**: It contains 2,700 high-quality samples organized into 8 primary reasoning dimensions and 18 sub-categories, spanning both real-world and game-world image editing tasks.
+-   **Reliable Dual-Reference Evaluation**: For each sample assessment, we design both the textual reference and ground-truth (GT) image reference. This multi-modal reference enables vision-language model (VLM) evaluators to perform direct and fine-grained comparisons at both the textual and visual levels with the generated images, leading to more reliable evaluation.

+
+## 🚀 Sample Usage
+
+To perform image editing with reasoning using UniREdit-Bagel, follow the steps below. This section is adapted from the [official GitHub repository](https://github.com/Maplebb/UniREditBench).
+
+### 1. Set Up Environment
+
+```bash
+conda create -n uniredit python=3.10 -y
+conda activate uniredit
+pip install -r requirements.txt
+pip install flash_attn==2.7.0.post1 --no-build-isolation
+```
+You can also install `flash_attn` via:
+```bash
+# for cuda11 torch2.5.x
+pip install "https://github.com/Dao-AILab/flash-attention/releases/download/v2.7.0.post1/flash_attn-2.7.0.post1+cu11torch2.5cxx11abiFALSE-cp310-cp310-linux_x86_64.whl"
+
+# for cuda12 torch2.5.x
+pip install "https://github.com/Dao-AILab/flash-attention/releases/download/v2.7.0.post1/flash_attn-2.7.0.post1+cu12torch2.5cxx11abiFALSE-cp310-cp310-linux_x86_64.whl"
+```
+
+### 2. Benchmark and Checkpoint Preparation
+
+First, prepare the UniREditBench benchmark dataset:
+```bash
+huggingface-cli download --resume-download maplebb/UniREditBench  --local-dir ./UniREditBench
+cd UniREditBench
+unzip original_image.zip
+unzip reference_image.zip
+cd ..
+```
+Then, prepare the UniREdit-Bagel checkpoint:
+```bash
+huggingface-cli download --resume-download maplebb/UniREdit-Bagel  --local-dir ./ckpt
+
+pip install safetensors
+
+python merge_ckpt.py
+```
+*(Note: The `merge_ckpt.py` script is part of the UniREditBench GitHub repository and should be run from its root directory after cloning and downloading the checkpoint.)*
+
+### 3. Inference
+
+Once the environment and checkpoints are prepared, you can run inference:
+```bash
+GPUS=8
+model_path=./ckpt
+input_path=./UniREditBench
+output_path=./output_images
+
+# Image Editing with Reasoning
+torchrun \
+    --nnodes=1 \
+    --nproc_per_node=$GPUS \
+    gen_images_mp_uniredit.py \
+    --input_dir $input_path \
+    --output_dir $output_path \
+    --metadata_file ./UniREditBench/data.json \
+    --max_latent_size 64 \
+    --model-path $model_path \
+    --think
+```
+This command will generate edited images based on the instructions and save them to the specified `output_images` directory. The `--think` argument enables reasoning capabilities.
