feat: implement window manager events

[okwasniewski]

Summary:

This PR implements window manager events, which solves #135.

Users will be able to listen to window state changes:

  React.useEffect(() => { 
    const listener = WindowManager.addEventListener('windowStateDidChange', (data) => {
      console.log('Window state changed to:', data);
    });
    return () => {
      listener.remove();
    };
  }, []);

The main window always has the id: 0
