/**
 * Mounts singleton overlay components (confirm modal/popover, notifications)
 * with the consumer app's context so globally registered components,
 * directives, i18n, and provide/inject all resolve correctly.
 *
 * The host element is appended to `container` (defaults to `document.body`).
 * For shadow-DOM / custom-element hosts pass the shadow root (or an element
 * inside it) so the overlays live within the shadow tree and inherit its
 * scoped styles — pair it with the `appendTo` prop so the teleported content
 * stays inside the same root.
 *
 * Plugin mode calls this automatically. Tree-shake consumers can either mount
 * `<VcPluginOverlays />` in App.vue or call this helper after `createApp`.
