/**
 * Assemble dist-cloudflare/ for the Cloudflare Worker deploy.
 *
 * Replicates the vercel.json route table with plain file placement so
 * Workers static assets (html_handling: auto) can serve every clean URL
 * without a rewrite engine:
 *
 *   dashboard/**  -> /            (routed pages, /js, /css, /docs, /blog, ...)
 *   dashboard/index.html -> /dashboard (as dashboard.html)
 *   site/**       -> /            (root landing page, catch-all winner)
 *   public/**     -> /            (og images, icons, robots.txt, sitemap.xml)
 *   dashboard/manifest.json -> /manifest.json  (PWA manifest wins over public/)
 *   llms.txt, llms-full.txt -> /
 *
 * /api/*, /openapi.json, /.well-known/x402 and /thread/* are handled by
 * worker/index.js (see wrangler.toml run_worker_first).
 *
 * Usage: node scripts/build-cloudflare.mjs
