The @mariozechner/clipboard native addon uses clipboard-rs, which is
X11-only and does not retain selection ownership after set_text resolves.
On Wayland-only compositors (Hyprland, Niri, ...) /copy reported success
without populating the clipboard. Skip the native addon on Linux and let
wl-copy/xclip/xsel handle text writes; they properly daemonize.
