Add YAML frontmatter metadata to Hugging Face README / Repo Card

[GabrielLidenor]

The Hugging Face repository displays the following warning:

YAML Metadata Warning: empty or missing yaml metadata in repo card

To resolve this, we need to add standard YAML metadata to the top of the repository card (README.md on Hugging Face). This metadata defines key attributes such as the task type, license, language, and dataset tags so HF can properly index the model.

Tasks

• Add the YAML block to the top of the repository card / README.md.
• Ensure Hugging Face successfully parses the frontmatter and the warning disappears.
