Crash regression for state machine conflicts: A test specifically checks that calling byobRequest.respond() after enqueue() doesn't crash the runtime. This sequence creates a conflict in the internal state machine — the enqueue() fulfills the pending read and should invalidate the byobRequest, but implementations must gracefully handle the subsequent respond() rather than corrupting memory in order to cover the very likely possibility that developers are not using the complex API correctly.
思路：单调递减栈，找「上一个比当前价格大的元素索引」。正序遍历，弹出所有 ≤ 当前价格的索引；跨度 = 当前索引 - 栈顶索引（栈空则为 当前索引 + 1）。
