ci(acceptance): add hang-proof Playwright smoke gate

[DavertMik]

What

Re-establishes an acceptance-level CI gate for 4.x. Today CI runs only unit/rest/runner suites; the only acceptance workflow is acceptance-tests.yml.disabled, which still targets the 3.x branch and a docker-compose WebDriverIO setup. The exact failure class blocking 4.0 (promise-composition hangs / broken error propagation) has zero CI signal.

This adds a hang-proof Playwright smoke job that runs the currently-passing subset on every PR, so the passing set can only grow.

Files

• test/acceptance/codecept.Playwright.smoke.js — an explicit allowlist config (tests: './{els,session,within}_test.js') of acceptance tests that pass reliably on the 4.x promise core.
• .github/workflows/acceptance-smoke.yml — push to 4.x + pull_request to **; timeout-minutes: 20 and an outer timeout 600 (defense-in-depth; exit 124 = hang); installs Chromium, boots the PHP test app, GET-polls health, runs the smoke suite, and uploads test/acceptance/output/ on failure.

Discovery (local, Node 22 / Playwright 1.59 / PHP 8.5)

Each acceptance file run individually under a hard timeout:

File	Result
els_test.js	PASS (30)
session_test.js	PASS (9 + 2 skipped)
within_test.js	PASS (12)
config_test.js	FAIL (7/1) — one scenario hits a JSON API that returns HTML locally; environment-flaky, not a promise-core failure → excluded
coverage_test.js	no @Playwright scenarios → excluded
retryTo_test.js	no @Playwright scenarios → excluded

The smoke suite is 52 passed / 2 skipped / 0 failed across three consecutive local runs (~58s each; includes the @Playwright gherkin before_hook.feature via the base config).

Maintenance

The smoke glob is an allowlist: when a promise-core fix makes an excluded file pass, move it into the glob in the same PR. The long-term goal is to delete this config and gate on the full codecept.Playwright.js.

Notes for reviewers

• No acceptance *_test.js file was edited, skipped, or tagged to make the gate green.
• The disabled 3.x acceptance workflow is left untouched.
• Defense in depth against runaway minutes: both timeout-minutes: 20 and the inner timeout 600.
