Improve model card: add metadata, paper link, and usage instructions

Hi! I'm Niels from the Hugging Face community science team. I noticed this repository could benefit from a more detailed model card.

This PR:
- Adds the `image-to-image` pipeline tag to improve discoverability.
- Adds metadata for the license (`cc-by-nc-4.0`) based on the non-commercial disclaimer in the GitHub README.
- Links the repository to the [associated paper](https://huggingface.co/papers/2606.20506) and project page.
- Includes a sample usage section with a code snippet for inference as found in the official GitHub repository.

-This repository contains LoRA checkpoints for FreeStyle CRef/SRef image editing.
+FreeStyle is a scalable dual-reference generation framework that allows for synthesizing images by combining the structure and semantics of a content reference with the style of a separate reference image. It leverages community LoRA weights as compositional anchors and introduces mechanisms like attention-level enrichment constraints and frequency-aware RoPE modulation to prevent content leakage from style references.

-The previous `freestyle-cref-sref-40000-no-rope/` folder name was corrected to `freestyle-cref-sref-40000-rope/` to reflect the RoPE inference requirement.
+## Sample Usage
+
+To generate an image using the FreeStyle model, you can use the inference script provided in the [official GitHub repository](https://github.com/Blue2Giant/FreeStyle).
+
+```bash
+cd model_infer
+# Follow environment setup instructions in the GitHub repository
+conda activate Sref
+
+python3 cref_sref_core_infer.py \
+  assets/00-cref.jpg \
+  assets/00-sref.jpg \
+  'Transfer the style of image 2 onto image 1, keeping image 1\'s layout.' \

+  --recaption_task_type style_transfer \
+  --out_dir outputs/demo \
+  --steps 28 --cfg 8 --seed 42 --overwrite
