PlasmaZones 3.1.3

Changed

• Rebuilt for KWin 6.1.2: the PlasmaZones KWin effect is compiled against a specific KWin version and will not load under a different one, so this release rebuilds the effect for KWin 6.1.2. Update to it once your system moves to that KWin, otherwise window dragging, shortcuts, and snapping stop working.
• Shorter KWin version-mismatch warning: when the installed effect was built for a different KWin than the one running, the notification now gives just the diagnosis and the rebuild-and-reinstall fix, without the NixOS-specific install note.
