Add pipeline tag and library name

This PR adds the `pipeline_tag: text-generation` and `library_name: transformers` metadata fields to the model card. This improves discoverability on the Hub and enables the automatic “Use in Transformers” snippet for users. The license and other existing metadata are preserved.
