stream: `pipeTo` with `preventCancel` can hit `ERR_INTERNAL_ASSERTION` if destination errors before deferred write

在 v24.16.0 上執行提供的重現，並與 v24.14.1 比較。檢查第 982 行的 node:internal/webstreams/writablestream 和第 1677 行的 node:internal/webstreams/readablestream，然後檢視 PR #61800；當回歸測試確認 preventCancel 因目的地錯誤而被拒絕，而不是因 ERR_INTERNAL_ASSERTION 被拒絕時，即表示完成。

stream

What steps will reproduce the bug?

const { ReadableStream, WritableStream } = require("node:stream/web");

let sourceController;
let destController;

const source = new ReadableStream({
  start(controller) {
    sourceController = controller;
  },
});

const dest = new WritableStream({
  start(controller) {
    destController = controller;
  },
  write() {},
});

source.pipeTo(dest, { preventCancel: true }).catch((err) => {
  console.log("pipeTo rejected:", err.name, err.message);
});

setImmediate(() => {
  destController.error(new Error("destination errored"));
  sourceController.enqueue("chunk");
});

How often does it reproduce? Is there a required condition?

Always.

What is the expected behavior? Why is that the expected behavior?

pipeTo() should reject with the destination error, like v24.14.1 does:

pipeTo rejected: Error destination errored

What do you see instead?

node:internal/assert:11
    throw new ERR_INTERNAL_ASSERTION(message);
          ^

Error [ERR_INTERNAL_ASSERTION]: This is caused by either a bug in Node.js or incorrect usage of Node.js internals.

Additional information

The error starts to occur in v24.15.0. This lines up strongly with https://github.com/nodejs/node/pull/61800.
