/**
 * Shared destination readiness hook.
 *
 * Call this from final destination client components to signal that the page UI
 * is ready and Flutter can remove its native loading cover.
 *
 * This hook only **requests** readiness — it does not directly interact with
 * the Flutter bridge. The root bootstrap script in layout.tsx owns actual
 * delivery and handles the case where HabibApp is injected late.
 *
 * @param ready - Whether the page considers itself visually ready.
 *                Pass `true` once critical data is available or the fallback
 *                UI is showing. The signal fires at most once per mount.
