Improve dataset card: Add task category, paper, code, project page links, and refined sample usage

This PR significantly improves the dataset card for HouseLayout3D by:
- Adding the `task_categories: ['image-to-3d']` to the metadata, enhancing discoverability for relevant tasks.
- Including explicit links to the official paper (https://huggingface.co/papers/2512.02450), the main GitHub repository (https://github.com/HouseLayout3D/houselayout3d), and the project page (https://houselayout3d.github.io) at the top of the card.
- Reformatting and expanding the existing "Getting Started" section into a comprehensive "Sample Usage" guide. This new section incorporates detailed installation steps (including `git-lfs`), instructions for downloading the dataset, and steps to run the visualization, all derived from the project's GitHub README for accuracy.

 # HouseLayout3D: A Benchmark Dataset for 3D Layout Estimation in the Wild
 
+[Paper](https://huggingface.co/papers/2512.02450) | [Project Page](https://houselayout3d.github.io) | [Code](https://github.com/HouseLayout3D/houselayout3d)
 
 **HouseLayout3D** is a challenging benchmark dataset for **3D layout estimation in large-scale, multi-floor buildings**. It is built upon real-world building scans from [Matterport3D](https://niessner.github.io/Matterport/), and provides detailed annotations of structural elements across up to five floors and forty rooms per building. The dataset is designed to support research in scene understanding, indoor mapping, and robotics applications that require vectorized, object-free representations of indoor spaces.
