Json Render Core

This is the foundation package for building AI-generated UIs from JSON specs. It gives you the primitives to define schemas, create component catalogs, and generate the system prompts that tell Claude how to output valid JSON. The real power is in the expression system: you get state binding, conditional rendering, computed props, and cross-field validation out of the box. If you're building a tool where Claude needs to generate UIs or structured interactions, this handles the schema layer and all the runtime resolution logic. It's framework agnostic and works with streaming JSONL output, so you can show progressive updates as Claude builds the spec.
