Proxy registry internals

Proxy components are created by combining a base renderer, all known HTML tags, and a Proxy lookup. When a property exists on the generated target, it is returned directly. Otherwise utilinent checks the requested category and then base in PluginManager.

This means Show.div is available immediately, while Show.Link appears after PluginManager.register({ show: { Link } }).

Caching

When a plugin-backed property is resolved, utilinent stores the specialized component on the current proxy target. Register plugins before rendering code that reads the property.
