📝 Walkthrough

Walkthrough

This pull request adds support for shield-styled badges (Shields.io style) to the badge registry endpoint, alongside the existing default badge style. The implementation introduces new rendering constants and functions to support both badge styles, includes a style parameter parser that accepts "default" or "shieldsio" options, and routes badge generation through style-specific renderers. Existing functionality like caching, headers, and error handling remains unchanged.
