Update library_name to transformers for improved Hub integration

This PR updates the `library_name` metadata tag from `peft` to `transformers`.

While PEFT is used for the model's efficient fine-tuning, the model is primarily loaded and used with the `transformers` library, building upon its `meta-llama/Llama-3.2-1B-Instruct` base. This change will enable the "Use in Transformers" code snippet and the inference widget on the model page, significantly improving user experience and discoverability on the Hugging Face Hub.

The rest of the model card remains excellent and comprehensive.
