This pull request improves the dataset card by:
- Setting the correct `task_categories` metadata to `image-text-to-text`.
- Replacing the `TODO_ARXIV_LINK` placeholder in the badge with the actual paper link on Hugging Face (`https://huggingface.co/papers/2607.06420`).
- Updating the Project Page and GitHub repository links to point to their official MM-MVR organization endpoints.
