Playwright Test analytics

Hi folks,

My name is Andrey, I'm a former Microsoft Playwright engineer.

I've noticed you're using Playwright Test and you even run [multiple shards](https://github.com/Comfy-Org/ComfyUI_frontend/actions/runs/27175867268/job/80226239104). I'd like to bring up the Flakiness.io project that we're building now to help track, fix & optimize tests: https://flakiness.io.

We just launched a new feature for Playwright Test - [balanced shards](https://github.com/flakiness/playwright#balanced-sharding). It should minimize the *makespan* of your sharded runs, so you'll get final results faster. I'd curious to see how it works on your workload.

In addition, you'll have all your tests in one place, on a single dashboard, with a performance, results & traces, for example https://flakiness.io/flakiness/pytest-flakiness.

Flakiness.io has a free plan for open source projects.

Let me know if you're interested - I'd be happy to help integrating and collecting the feedback.

The issue names Playwright Test, sharded GitHub Actions runs, and Flakiness.io, but mentions no repository files, tests, or entry points. First determine whether the project wants this external integration; the scope, implementation location, and definition of done are not specified.
