/**
 * Bundle smoke check — the ONLY test that exercises the built artifacts
 * (lib/client.js). The vitest suite tests src/ directly and never builds;
 * this script exists because the packaging glue itself (the
 * `window.__ModuleLoader__.load({id, factory})` handoff, the CSS channel's
 * data-plugin style tag, platform-module requires) only exists after tsdown
 * runs. It is opt-in: run `pnpm run build && pnpm run test:bundle`.
 *
 * Everything here runs against the REAL bundle in jsdom with REAL React and
 * the REAL ui-primitives — only the harness services (locale/slots/effects)
 * are in-memory implementations of their documented contracts.
 *
 * Exit code 0 on success, 1 on failure.
