This PR significantly improves the model card for `MomaGraph-R1` by making the following updates:
- Adds `pipeline_tag: image-text-to-text` to the metadata, enabling better discoverability and the inference widget on the Hugging Face Hub.
- Adds `library_name: transformers` to the metadata, as indicated by the presence of `transformers_version` and `Qwen2_5_VLForConditionalGeneration` in `config.json`. This will enable the automated "how to use" code snippet.
- Adds a comprehensive model description based on the paper abstract.
- Includes links to the official paper, project page, and GitHub repository in the model card content.
- Adds a "Usage" section that directs users to the GitHub repository for code examples and a "Citation" section.
Please review and merge if these improvements align with the project goals.
