/**
* @wrnexus/ui registry — SERVER-ONLY filesystem helpers for discovering the
* package's `.wrn` component sources and stylesheet on disk.
*
* This is the code that used to live in `index.ts`. It was moved here
* because it depends on `node:fs`/`node:path`/`node:url`, which don't exist
* in a browser build — and `index.ts` is the package's main entry, so any
* client-side (browser) bundle that reaches ANY `@wrnexus/ui` component
* transitively tried to bundle this file too, failing with:
* "Browser polyfill for module 'node:url' doesn't have a matching export
* named 'fileURLToPath'"
*
* Import from `@wrnexus/ui/registry` (server-side code only — CLI,
* dev-server, build). Never import this from a `.wrn` component or anything
* that can end up in a client runtime bundle.
