Add pipeline tag, paper and code links

Hi! I'm Niels from the Hugging Face community team. I've updated your model card to include the `text-to-3d` pipeline tag and added links to your paper and GitHub repository. This will make the model more discoverable on the Hub and provide users with easy access to the underlying research and implementation.

 # CubePart: An Open-Vocabulary Part-Controllable 3D Generator
 
+This repository contains the checkpoints for **CubePart**, a generative framework for open-vocabulary, part-controllable 3D mesh generation. Given a global text prompt and a user-defined parts schema, CubePart generates a set of meshes that assemble into a coherent object while respecting the specified semantic structure.
