[Feature]: Support `.zip` files in `playwright show-report`

[seanlafferty-ibm]

🚀 Feature Request

We produce the standard playwright report in github CI as an artifact (which github automatically zips). We download this report to view playwright traces/screenshots. It's a bit of a pain because you have to download the github zip, extract it, and then point the show-report command at it.

playwright show-report my/unzipped/report

It would be less clicks if playwright show-report natively supported reading a zip'd report.

Example

No response

Motivation

Less friction for debugging tests that fail in CI

Hi, I'd like to try implementing this.
From what I can see, the change would live in the show-report CLI command handler, likely in packages/playwright/src/cli.ts or wherever the show-report subcommand is dispatched. The core logic would be to detect if the provided path has a .zip extension, extract it to a temp directory (using Node's zlib or a library like adm-zip) and then pass the extracted path to the existing report server. On process exit or SIGINT the temp dir should be cleaned up.
A few things I want to confirm before starting:
Is there a preferred zip library already used elsewhere in the codebase, or should I use Node's built-in zlib/stream APIs?
Should the temp dir cleanup be best-effort (fire and forget on exit) or should it block until cleanup completes?
Is cross-platform path handling for the zip extraction already abstracted somewhere I should reuse?
Happy to open a draft PR once I have a working prototype if that's useful for early feedback.
