This PR updates the model card metadata by:
- Removing the `arxiv:2609.33437` tag from the YAML metadata; the arXiv ID remains linked in the Markdown content.
- Adding `pipeline_tag: image-classification` so the model is categorized correctly on the Hub.
No `library_name` is added because the model is loaded with custom SMAT code rather than a standard Hugging Face library loader. The model card body is unchanged.
