On Linux / Wayland the desktop can't strip the window frame at runtime,
so turning on custom window chrome drew the Lotus titlebar inside KDE's
frame (two sets of window buttons). The desktop's `set_custom_chrome`
now answers whether the frame is stripped right now; the titlebar and
layout follow that answer (falling back to the setting for older
desktop builds), so there's never two titlebars or none. The setting
says it applies on next start on Linux / Wayland.
