Type Alias EventListenerVec 

pub type EventListenerVec = SmallVec<[(Rc<RefCell<EventCallback>>, EventCallbackConfig); 1]>;

Vector of event listeners, optimized for the common case of 0-1 listeners per event type. Uses SmallVec to avoid heap allocation when there’s only one listener. Inspired by Chromium’s HeapVector<…, 1> pattern for event listener storage.
