GDK_BACKEND/QT_QPA_PLATFORM forced to wayland stripped toolkits' fallback,
killing X11-only builds like emacs-gtk ('cannot open display' against a
healthy Xwayland). Children now self-select from WAYLAND_DISPLAY/DISPLAY,
and XAUTHORITY is cleared.
Separately, X11 membership decisions moved from window-creation time to
first map: GTK leader windows never map, yet claimed the tab slot at
creation, leaving a permanent black tab while the real frame was demoted
to a stacked member -- and Alt-cycling onto that phantom main member
crashed on wlr_seat_keyboard_notify_enter(NULL). Never-mapped windows now
free silently; keyboard-entry paths guard on live surfaces. New
tests/xleader.c probe (unmapped leader + mapped frame) locks the behaviour
in.
