Improve model card: Update paper/code links and BibTeX citation

This PR enhances the model card for `ByteDance/Ouro-1.4B-Thinking` by:

* Updating the "Paper" link under "Project Links" to point directly to the Hugging Face paper page ([Scaling Latent Reasoning via Looped Language Models](https://huggingface.co/papers/2510.25741)) for improved discoverability on the Hub.
* Adding an explicit "Code" link under "Project Links" to the official GitHub repository (`https://github.com/Ouro-LLM/Ouro`), which is linked from the project page.
* Updating the BibTeX citation to include the full list of authors and a direct link to the arXiv paper for better attribution and accuracy.

These changes make it easier for users to access the paper, code, and correctly cite the work.
