dbus-update-activation-environment and systemctl --user import-environment were fired asynchronously via spawn_async_no_shell, racing with the autostart script. Any systemd user service started from autostart (e.g. via labwc-session.target) could start before the import completed, leaving WAYLAND_DISPLAY and related variables absent from its environment and those of any apps it launches. Run both commands synchronously via a new spawn_sync_no_shell helper so the import is guaranteed to complete before the autostart script executes.
