/**
 * Adds the preconnect hints to the host page. Safe to call more than once: a
 * hint the host page or the VGS vendor already added is left alone.
 *
 * The work waits for one microtask. `@vgs/collect-js` adds its own hints from a
 * microtask that it queues when the bundle evaluates, which is always before
 * this call, so the wait lets that hint arrive first and keeps the VGS target
 * from becoming a duplicate. If the vendor ever stops, the VGS target above
 * still warms the origin.
