Research direction
Start at Hyperf\Crontab\Strategy\Executor::execute and reproduce the */5 * * * * * schedule described in the issue. Trace the final timer callback delay and verify that executions occur at 0, 5, 10 seconds rather than 1, 6, 11 seconds; done means the observed timing matches the stated schedule.

Description
比如*/5 * * * * *，本应该每5秒执行一次，也就是0秒、5秒、10秒...时间执行，实际时间为1秒、6秒、11秒...，跟踪了下代码，发现Hyperf\Crontab\Strategy\Executor的execute方法最后一行是$callback && $this->timer->after($diff > 0 ? $diff : 1, $callback);，不明白为什么这么设计，这不是跟预期不一致吗？
