plugin-hook-registration

@myadmin-plugins

Adds a new Symfony EventDispatcher hook to src/Plugin.php. Use when user says 'add hook', 'register event', 'add settings', 'add page requirement', or 'add menu item'. Handles getHooks() return array, GenericEvent $event handler signature, and getRequirements() page registration. Do NOT use for modifying existing hooks or creating new plugin packages from scratch.
