### Is Your Feature Request Related to a Problem? 当 RocketMQ 的 Pop 消费模式引入了按需唤醒的特性（#8269，#8592）后，消费延迟滞后时间最大会达到一个长轮询的时间间隔，实际上消费过程是没有延迟的。为了更准确地反映这一情况，系统在计算消息堆积量之前会先执行一次长轮询以唤醒消费者。这一特性依赖于两个条件：1. 每写入一定数量的消息时触发唤醒；2. 在输出指标之前执行唤醒逻辑。 When the wake-up feature was introduced in RocketMQ's Pop consumption mode (issues #8269, #8592), the maximum backlog of messages is equivalent to the duration of one long poll, meaning that the actual consumption process is delay-free. To more accurately reflect this situation, the system now performs a long poll to wake up the consumer before calculating the message lag. This feature relies on two conditions: 1. Triggering a wake-up after a certain number of messages are written; 2. Executing the wake-up logic before outputting the metrics. ### Describe the Solution You'd Like Impl this feature ### Describe Alternatives You've Considered This feature relies on two conditions: 1.
