Subject: [PATCH 1/6] add Playwright E2E tests for frontend AJAX security
 (WP-1011)

Adds Playwright infrastructure to catch the class of bug where backend
nonce checks are added without updating legacy PHP-rendered JavaScript.

Core test (ajax-security.spec.js) intercepts every admin-ajax.php POST
on the post edit and bulk submit pages, asserts _wpnonce is present in
each request, and asserts no 403 responses. This test would have caught
the WP-1007 regression in ContentEditJob.php.

CI integration: Node.js 20 + Playwright Chromium baked into the Docker
image; test.sh starts a PHP built-in server before PHPUnit and exits
non-zero if either E2E or PHP tests fail.

Subject: [PATCH 2/6] fix Playwright CI: global install, drop runtime npm ci
 (WP-1011)

- Dockerfile: install @playwright/test globally (npm install -g) so
  test.sh has no dependency on package-lock.json at runtime
- test.sh: drop the npm ci step; use 'playwright' binary directly
  (available globally in the Docker image)
- Commit package-lock.json for reproducible local npm install

Fixes: npm ci failing (no lockfile), then npx downloading wrong
playwright version (1.61.1 instead of @playwright/test@1.47.2).

Subject: [PATCH 3/6] fix Playwright: set NODE_PATH so global @playwright/test
 resolves (WP-1011)

require('@playwright/test') in playwright.config.js fails when running
from the project dir because Node's resolution never reaches the global
prefix. NODE_PATH=$(npm root -g) makes the global install visible.

Subject: [PATCH 4/6] fix Playwright: normalize siteurl and explicit --docroot
 for wp server (WP-1011)

wp server uses the CWD as document root when --docroot is not specified.
At the point the server is started, CWD is ${PLUGIN_DIR}/inc/third-party/bin,
so WordPress files ended up accessible at http://test.com/WP_INSTALL_DIR/
instead of http://test.com/. This caused wp_login_url() to generate
redirect URLs with /WP_INSTALL_DIR in the path, breaking the auth setup.

Also reset siteurl/home to http://${E2E_DOMAIN} before starting the server
as a defensive measure in case multisite-convert left a stale path in the
options table.

Subject: [PATCH 5/6] fix Playwright: use php -S directly instead of wp server
 (WP-1011)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

wp server --docroot is unreliable across wp-cli versions — the previous
commit showed the server stopped responding entirely when --docroot was
added. Switch to php -S 0.0.0.0:80 -t WP_INSTALL_DIR which is explicit
and unambiguous: document root is always WP_INSTALL_DIR.

Our test URLs (wp-login.php, wp-admin/post.php, wp-admin/admin.php) are
direct PHP files so WordPress rewrite routing is not needed, making the
wp server router script unnecessary.
