/**
 * `quickback dev` — local dev orchestrator.
 *
 * Resolves the named-subdomain URLs from `dev.hostnames` (see
 * research/portless-local-dev-spec.md), prints them, and runs `wrangler dev`.
 *
 * Cross-subdomain cookies/CORS + host-routing + runtime-config are compiled into
 * the worker. For named-subdomain mode this command also runs wrangler dev with
 * the production `custom_domain` routes stripped — wrangler dev pins the
 * simulated host to those routes, so removing them lets it honor the real
 * request Host and serve EVERY *.{base} subdomain at once on one port (no
 * `--host`, no proxy needed for the functional demo; a proxy only adds clean
 * `:80` URLs).
