Subject: [PATCH] WS-1: Canonical- & OpenGraph-Meta zentral im Web-Layout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Ergänzt web-master.blade.php um <link rel="canonical">, OpenGraph- und
Twitter-Card-Tags. Self-Canonical-Default wird portal-getrennt aus der
Portal-URL ($domainUrl) + Request-Pfad gebaut – bewusst nicht aus
url()->current(), da URL::forceRootUrl sonst alle Portale fälschlich auf
pressekonto.test kanonisieren würde. Seiten können canonical/meta_description/
og_type/og_image per @section überschreiben; release-detail als article
ausgezeichnet. Erfüllt die Canonical-Hygiene aus dem Duplicate-Content-Update §5.

Tests: tests/Feature/Web/CanonicalMetaTest.php (inkl. Cross-Portal-Negativtest).
