在评论区里提到了 async_simple 在没有调度器的特定情况下的爆栈问题

Start with the linked Zhihu article and reproduce the reported stack overflow in async_simple when no scheduler is present. Trace the no-scheduler execution path in the repository and identify the conditions that trigger the overflow. Done means the reported case no longer overflows and the behavior is covered by a regression test.
