TauriUpdateFeature component in ClientNonUIFeatures checks for updates
on mount and every 12h (skips if checked within the window). On update
available, fires a Lotus toast: "Lotus Chat vX.Y.Z is ready to install."
Clicking the toast calls install(). No-op on web (isTauri guard).
Also adds optional onClick to ToastNotif type and wires it in
LotusToastContainer so custom click handlers can skip hash navigation.
