Run PHPStan on WordPress codebases with correct stubs baselines and narrow ignores

This entry turns WordPress/agent-skills' WP PHPStan guidance into a bounded agent workflow for plugin, theme, and site repositories. The agent inspects the existing PHPStan setup, adds or verifies WordPress-aware stubs, tightens config paths, and fixes or documents only the narrow ignores and baseline changes needed to get useful static-analysis output.

Prerequisites

PHP, Composer, PHPStan, and a WordPress plugin, theme, or site repository
