Update dataset card: License, task category, paper link, and abstract

This PR updates the dataset card for the SEAM benchmark by making the following improvements:

- **Metadata `license`**: Updated from `mit` to `cc-by-nc-4.0` to reflect the license specified in the associated GitHub repository.
- **Metadata `task_categories`**: Added `image-text-to-text` as a primary category, which accurately describes the multimodal reasoning tasks, alongside existing categories (`visual-question-answering`, `multiple-choice`).
- **Content Paper Link**: Updated the main "Paper" link to point to the Hugging Face Papers page: [https://huggingface.co/papers/2508.18179](https://huggingface.co/papers/2508.18179).
- **Content Project Page**: Renamed the "Leaderboard" link to "Project Page / Leaderboard" to better reflect its role as the project's official website.
- **Content Abstract**: Updated the abstract section to precisely match the official paper abstract for accuracy.

These changes ensure the dataset card is more informative, discoverable, and aligned with current best practices.

 ## Abstract
 
-Evaluating whether vision–language models (VLMs) reason consistently across representations is challenging because modality comparisons are typically confounded by task differences and asymmetric information. We introduce **SEAM**, a benchmark that pairs semantically equivalent inputs across four domains with existing standardized textual and visual notations. By employing distinct notation systems across modalities, in contrast to OCR-based image-text pairing, SEAM provides a rigorous comparative assessment of the textual-symbolic and visual-spatial reasoning capabilities of VLMs. Across 21 contemporary models, we observe systematic modality imbalance: vision frequently lags language in overall performance, despite the problems containing semantically equivalent information, and cross-modal agreement is relatively low. Our error analysis reveals two main drivers: textual perception failures from tokenization in domain notations and visual perception failures that induce hallucinations. We also show that our results are largely robust to visual transformations. SEAM establishes a controlled, semantically equivalent setting for measuring and improving modality-agnostic reasoning.
