This PR adds a comprehensive model card for the OmniTry model, including:
- An overview of the model and its capabilities based on the paper abstract.
- Links to the paper ([OmniTry: Virtual Try-On Anything without Masks](https://huggingface.co/papers/2508.13632)), project page (https://omnitry.github.io/), and GitHub repository (https://github.com/Kunbyte-AI/OmniTry).
- Links to the Hugging Face Space demo and benchmark dataset for easy access.
- Clear instructions for setting up the environment and running the Gradio demo, serving as sample usage.
- Relevant metadata: `pipeline_tag: image-to-image` and `library_name: diffusers`, ensuring better discoverability and integration on the Hub.
This improvement makes the model more accessible and understandable for users.
