The frameless custom chrome (D-057) is gated on HAS_WAYLAND_CLIENT, which
was only defined when CMake's non-required wayland-client check happened
to find it. A build host/container without the Wayland client dev headers
(plausible on Bazzite/immutable distros that build in a distrobox) silently
compiled the decoration-suppression out, so the rebuilt app shipped the
compositor's native title bar (double title bar on KDE Plasma Wayland).
Make wayland-client a hard requirement: fail the configure with an
actionable message (Fedora wayland-devel / Debian libwayland-dev) rather
than drop a core feature. Fix the stale "xdg-decoration" comment — the
code uses the KDE server-decoration protocol.
