The `registered` flag was one-way: set true once the tray registered, but
never cleared if the StatusNotifierWatcher later disappeared (panel restart,
tray plugin disabled, tray app killed). After that, a Wayland close-to-tray
would destroy the window into a tray that no longer exists, with no recovery
short of SIGTERM.
Implement ksni's `watcher_online`/`watcher_offline` callbacks to keep the
shared flag in sync. On offline, also force the window back (idempotent
`show()`) so a window that was already hidden when the watcher died isn't
stranded, and return true to keep the service alive for re-registration.

Replace eframe::run_native with a winit ApplicationHandler + glutin +
egui_glow loop so "keep running in the tray" can genuinely hide the
window. winit's set_visible(false) is a deliberate no-op on Wayland
(xdg-shell has no unmap-but-keep-alive request), so the only way to hide
a toplevel is to destroy its surface: hide-to-tray now drops the Window +
GL surface (parking the GL context as not-current) and a tray click
recreates them and makes the context current again. The GL context,
glutin display/config, egui_glow painter (uploaded textures), and
egui-winit state (clipboard) all persist across the cycle — only the OS
window and its surface churn.
Wakeups route through winit's EventLoopProxy (the new Waker, and the
tray) instead of egui's repaint callback, so a child event or tray click
wakes the loop even while the window is dropped and no frame is running —
keeping viewer join/leave notifications and the tray tooltip live while
hidden. Removes the old Wayland minimize-to-tray fallback (window stayed
in the taskbar); hide is now uniform on Wayland and X11.
Deps: winit/glutin/glutin-winit/egui_glow promoted to direct (gui-gated,
optional) — all already transitive via eframe, so no new crates. winit's
default features minus wayland-csd-adwaita, so sctk-adwaita/tiny-skia/
ttf-parser aren't pulled for a CSD fallback titlebar (KWin draws
server-side decorations, and eframe never had CSD either).
Verified end-to-end on KWin Wayland: launch->render; close->window AND
taskbar entry gone (true hide, process stays alive); tray activate->
window + GL surface recreated and renders; tray quit->clean exit; stderr
clean throughout. cargo test --features gui: 15 pass; clippy clean;
headless dependency tree unchanged.

Add a StatusNotifierItem tray (ksni — pure-Rust over the zbus stack
notify-rust already pulls; only new crate is the pastey macro helper).
The icon reflects host/viewer status via its tooltip and offers
Show / Quit; it runs on its own thread, channel-wired to the egui app.
Add a Settings screen with a persisted toggle 'keep running in the tray
when I close the window' (config.toml [gui] close_to_tray), defaulting
OFF so the close button quits as users expect. When ON, closing hides
to the tray on X11 / minimizes on Wayland (which has no protocol to hide
a toplevel) and keeps any live stream running. If no tray is present the
close behaves normally, so the window can never be stranded.
