Add Robotics tag and metadata

Hi! I'm VB from Hugging Face. Congratulations on your model! I'm opening a quick PR to update the model card to add Robotics metadata.

This PR adds standard Robotics metadata to the model card:
- Added 'Robotics' to tags
- Set pipeline_tag to 'robotics'

These changes help improve discoverability of robotics-related models on the Hugging Face Hub.
