70 * 1. First click:
71 *    - Initializes Yana chatbot via iTuffyStarter()
72 *    - Marks launcher as "started"
73 *    - Opens chatbot after short delay (SDK needs time to initialize)
74 *
75 * 2. Subsequent clicks:
76 *    - Checks if chatbot is currently open using isPopupOpen()
77 *    - If closed → opens chatbot
78 *    - If already open → does nothing (launcher is "open-only")
79 *
80 * Notes:
81 * - We DO NOT call isPopupOpen() before initialization (avoids SDK bug)
82 * - We guard all SDK calls to prevent runtime errors if not ready
