KDE Plasma Tightens Wayland Focus Management to Prevent Focus Stealing

KDE Plasma's window manager, KWin, is enhancing Wayland's window focus management. Previously, focus stealing in X11 was frustrating and even a security risk. Wayland uses the XDG Activation protocol to mitigate this, but some applications still violate it. KWin's new "Extreme" focus stealing prevention setting will enforce the use of valid tokens for window activation, eliminating focus stealing and improving user experience. This update fixes focus issues in applications like Dolphin and KRunner and improves backend DBusRunner activation token management.
