• Fixed: Wi-Fi setup hotspot disappearing after ~15 seconds.
  When the device couldn't connect to Wi-Fi and the user pressed the BOOT
  button to open the setup hotspot, the hotspot would appear briefly then
  vanish — making it impossible for phones or laptops to find and connect to
  it. This was caused by a background Wi-Fi reconnection task that was
  already in progress when the hotspot was activated. After its 15-second
  connection timeout expired, it shut down the entire Wi-Fi radio (including
  the hotspot) as part of its cleanup. The fix adds checks throughout the
  reconnection code so that once setup mode is activated, all pending
  reconnection attempts abort cleanly without touching the Wi-Fi radio.
