This PR significantly enhances the model card for the `FACM` model.
Key improvements include:
- Adding `pipeline_tag: unconditional-image-generation`, enabling the model to be found under this pipeline tag (e.g., at https://huggingface.co/models?pipeline_tag=unconditional-image-generation).
- Specifying `library_name: diffusers`, which helps with integration and displaying the "how to use" button for `diffusers` library.
- Including additional `tags` (`flow-matching`, `consistency-models`, `latent-diffusion`, `imagenet`) for better discoverability.
- Linking to the official paper ([Flow-Anchored Consistency Models](https://huggingface.co/papers/2507.03738)) and its abstract.
- Providing a direct link to the official GitHub repository (https://github.com/Peterande/FACM).
- Integrating the performance metrics table and detailed "Quick Start" instructions for inference and training from the original repository.
- Adding the BibTeX citation and acknowledgements.
