fix: race condition in writeStats

[colinaaa]

Summary

Fix a race condition that the writeStats would resolve before the FS operation finished, which may lead to incorrect content in stats.json.

Now instead of manually listen to the end and error event, we use the pipeline API from node:stream/promise to handle error and promise resolving for us. The pipeline API has been added in Node.js v15.0.0, which should work since we have engines.node >= 20.9.0 now.

What kind of change does this PR introduce?

a fix

Did you add tests for your changes?

Yes. And the test would fail without the fix.

Does this PR introduce a breaking change?

No.

If relevant, what needs to be documented once your changes are merged or what have you already documented?

Nothing.

Use of AI

Yes. We use AI to find the race condition in writeStats function and use AI to generate the fix and the test.

I've read and understanded every line of the code I submitted.

Looks good to me! Would you be so kind and write a changelog entry under the UNRELEASED section and this this as a bug fix?
