/**
 * Schema export.
 *
 * Run: `npm run schemas:export` (after build) — writes every registered
 * anyvali schema to /schemas/<key>.av.json. The output is portable: Rust kiosk
 * + Node-RED nodes + the browser (via vendored @anyvali/js) all consume these
 * exact files.
 *
 * Also copies the JSON into server/src/web-static/schemas/ so the browser
 * fetches them via /static/schemas/<key>.av.json with no extra plumbing.
