@myadmin-plugins

Adds a new Symfony EventDispatcher hook to src/Plugin.php following the getHooks() pattern: register event name → [Plugin::class, 'methodName'], implement as public static method accepting GenericEvent. Use when user says 'add hook', 'new event handler', 'plugin event', 'register hook', 'listen to event'. Do NOT use for OpenSRS API wrapper methods in OpenSRS.php, CLI bin/ scripts, or test files.
