ThrottledNotifier class
帧对齐、带"无监听者不调度"的轻量通知器。 Frame-aligned, no-listener-no-schedule notifier.
与 ChangeNotifier 不同：同一帧内的多次 notifyThrottled 合并为一次 （下一帧绘制后触发），且当没有任何监听者（面板未挂载）时完全不调度，省电。 Unlike ChangeNotifier, repeated notifyThrottled in the same frame coalesce into one (fired after the next frame paint), and when there is no listener (panel not mounted) it schedules nothing — saving power.
