Subject: [PATCH] style: declare(strict_types=1) on PSA_Upgrade to match
 project pattern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

QA caught this on 37aa0c8 — every other includes/class-psa-*.php in the
codebase declares strict_types at the top. The new class should match.
