test: Update example packages to use playwright instead of jest + puppeteer

[Joshua Smithrud (Josmithr)]

Migrate the repository's example packages and related DevTools end-to-end tests from Jest + Puppeteer to Playwright. This removes the Jest-Puppeteer configuration and type workaround package, adds shared Playwright configuration, and updates build and CI wiring to run and publish Playwright test results.

The client-utils browser hash tests bundle and execute the production browser entry point so regressions in the browser implementation cannot be masked by copied test logic.

To facilitate the new Playwright configurations, Tinylicious now supports selecting its listening port via command line argument.

Hi! Thank you for opening this PR. Want me to review it?

Based on the diff (7621 lines, 266 files), I've queued these reviewers:

• Correctness — logic errors, race conditions, lifecycle issues
• Security — vulnerabilities, secret exposure, injection
• API Compatibility — breaking changes, release tags, type design
• Performance — algorithmic regressions, memory leaks
• Testing — coverage gaps, hollow tests

Pull request overview

This PR migrates the repository’s example packages (and related devtools e2e apps) from jest + puppeteer to Playwright, updates CI/pipeline wiring to run the new Playwright test suite, and removes now-unneeded puppeteer/jest-puppeteer configs and type workarounds.

Changes:

• Add Playwright configs and update example/devtools test code to use @playwright/test.
• Remove Jest + Puppeteer configs/dependencies (and the internal @types/jest-environment-puppeteer workaround package).
• Wire up CI/build tooling to recognize and run test:playwright (pipeline + repo policy checks + fluid-build task graph).

I found two issues in the client-utils portion of this migration:

1. packages/common/client-utils/src/test/playwright/gitHash.test.ts: the replacement no longer exercises the production browser hashing implementation. The previous Jest test used rewire to invoke digestBuffer and encodeDigest from hashFileBrowser.js; the new test imports the Node entry point and independently reimplements those browser operations in browserHash/encodeDigest. A regression in the production browser implementation can therefore pass while the copied implementation remains correct. Could we run the actual browser entry point in the page, for example through a small browser bundle that imports indexBrowser.js?

2. packages/common/client-utils/package.json: fluidBuild.tasks now defines build:test:mocha:cjs, build:test:mocha:esm, and build:test:types twice. The values currently match, so behavior is unchanged, but JSON parsing silently keeps only the later copies and future edits to the earlier definitions would be ignored. Please keep one definition for each key and add only build:test:playwright in the new block.

[Alex Villarreal (alexvy86)]

One behavior change seems worth calling out in the PR description: the old Jest-Puppeteer configs used usedPortAction: "error", whereas the Playwright configs use reuseExistingServer: !process.env.CI. CI still fails on a port conflict, but local test runs will now reuse a process already listening at the assigned URL instead of rejecting it. That is probably a useful local-development improvement, but it could also connect a test to a stale or unrelated server, so documenting the intentional tradeoff would help reviewers and future maintainers.

[Alex Villarreal (alexvy86)]

I did a joint pass over the whole PR with an agent (didn't look at every single file myself) and I think the change is sound. I can approve once the merge conflict is addressed and the 2 points in #27964 (comment) have been considered.

I went ahead and reverted this behavioral change. We can always reconsider this later, but that minimizes the scope of change here.
