feat(gui): desktop notification when a viewer joins or leaves

Browse Source 
The host screen pops a desktop notification on each viewer join/leave,
so you know someone connected while the window is in the background.

Fired on a detached thread (the D-Bus call never touches the egui
frame) and gated on the same viewer-list transitions, so stopping the
host — which drops the child and stops pumping events — doesn't spray a
notification per remaining viewer.

notify-rust's default features give the pure-Rust zbus backend, so this
adds no system libdbus dependency and no GTK event loop (gui feature
only; the headless build is untouched).
