Pull request overview

Updates AMP-related test fixtures and URL rewriting logic to handle multiple AMP cache hosts (notably ampjs.org) and stabilizes test inputs/outputs across the suite.

Changes:

• Update AMP video test fixtures to use a more stable Big Buck Bunny MP4 URL.
• Extend AMP cache host handling to recognize and rewrite both cdn.ampproject.org and ampjs.org, and update RewriteAmpUrls expected outputs (including preloads).
• Refresh runtime fallback metadata, align PHPCompatibility checks with the project’s PHP minimum, and adjust CI workflow triggering behavior.

src/Amp.php:74

• Amp::CACHE_HOSTS now allows both cdn.ampproject.org and ampjs.org, but CACHE_ROOT_URL is still hard-coded to the cdn host. Call sites that gate on CACHE_ROOT_URL (e.g. AutoExtensions.php:197 and Html/Parser/ScriptTag.php:219) will still ignore ampjs.org URLs, leading to inconsistent behavior depending on which code path is used.

     * URL of the AMP cache.
     *
     * @var string

    const CACHE_ROOT_URL = self::CACHE_HOST . '/';
