Add library name, code link and citation

This PR improves the model card by:
- Adding `library_name: transformers` to the metadata to enable the "Use in Transformers" button.
- Adding a link to the official GitHub repository for the [Four Over Six](https://github.com/mit-han-lab/fouroversix) quantization method.
- Adding the BibTeX citation for the research paper.

 # Wayfarer-2-12B-NVFP4-FP8
 
 Quantized weights of the [Wayfarer-2-12B](https://huggingface.co/LatitudeGames/Wayfarer-2-12B) model for use with nVidia Blackwell GPUs, in a hybrid format using NVFP4 with [Four Over Six](https://arxiv.org/abs/2512.02010) adaptive block scaling for the MLP layers and `FP8_DYNAMIC` for the self-attention layers. More information about the hybrid format [here](https://huggingface.co/DataSnake/Mistral-Nemo-Instruct-2407-NVFP4-FP8), but the short version is that FP8 attention has minimal impact on speed and VRAM usage while making a marked difference in output quality, especially at longer context lengths.

 ## Inference
 Tested on a RTX 5060 Ti 16GB with [Aphrodite Engine](https://github.com/aphrodite-engine/aphrodite-engine) and [vLLM](https://github.com/vllm-project/vllm). It requires compressed-tensors 0.14.0 or later, so you'll have to update the version in your venv if you use Aphrodite Engine 0.10.0 or an older version of vLLM. On my system, Aphrodite Engine 0.10.0 was able to run the checkpoint with a 32k context window with the `--single-user-mode` flag, while vLLM 0.20.0 and Aphrodite Engine 0.20.0, which don't have that flag, were able to do the same with `--max-num-seqs 1 --cudagraph-capture-sizes 2` flags, though with the caveat that each crashed with OOM errors the first time they ran the model but ran fine from the second time onwards.
