Subject: [PATCH 1/2] Added a Windows-only helper
 (mg_win32_allow_autohide_taskbar) that gets the native HWND and calls
 SetWindowPos(..., HWND_NOTOPMOST, ...) for non-fullscreen window-state
 transitions, so a maximized ZoiteChat window no longer blocks the taskbar
 auto-hide reveal edge. Hooked that helper into mg_windowstate_cb so it runs
 whenever the main window state changes (while preserving existing
 maximize/fullscreen preference handling).
