[Vercel JSON Render] Official HeroUI v3 registry package

## Summary Requesting an official HeroUI v3 integration package, similar to the existing `@json-render/shadcn`. ## Motivation HeroUI v3 (beta) is a React component library built on React Aria Components and Tailwind CSS v4. It uses a compound components pattern (e.g., `Card.Header`, `Card.Content`, `Button.StartContent`) which differs from flat-prop component APIs. Having an official registry would lower the barrier for HeroUI users adopting json-render, rather than each team building custom registry mappings. ## Considerations HeroUI v3's compound component pattern may need special handling in the registry layer, translating flat catalog props into nested compound component structures. For example: ```tsx // Catalog defines flat props Card: { props: { title, description }, hasChildren: true } // HeroUI v3 renders as compound components <Card> <Card.Header>{title}</Card.Header> <Card.Content>{description}</Card.Content> {children} </Card> ``` ## References - HeroUI v3 d
