PlasmaZones 1.13.0

Added

• Layout Picker Overlay: Full-screen interactive layout browser triggered via configurable keyboard shortcut. Browse all available layouts in a centered card grid with keyboard navigation (arrow keys + Enter) and mouse support. Selecting a layout switches to it and resnaps all windows. (#176)
• Shared LayoutCard component: Extracted reusable LayoutCard.qml and PopupFrame.qml into org.plasmazones.common QML module, shared between the Zone Selector and Layout Picker overlays.
• Snap Assist after resnap: Snap Assist now triggers after resnapping windows when switching layouts via the layout picker, offering to fill any empty zones.

Fixed

• Zone activation broken when Zone Selector disabled (#175): Disabling the Zone Selector popup caused the zone activation hotkey (e.g. Alt+drag) to stop working entirely. The root cause was that D-Bus deserialization of trigger settings could silently fail (Qt delivering QDBusArgument instead of native QVariantList<QVariantMap>), but this was masked when zoneSelectorEnabled=true because a bypass gate let all drag events through regardless. Added robust QDBusArgument unwrapping, a permissive m_triggersLoaded flag that allows drags through until triggers are confirmed loaded, and diagnostic logging for trigger load failures.
• Layout Picker double-trigger: Rapidly pressing the layout picker shortcut could create multiple overlay windows with competing KeyboardInteractivityExclusive keyboard grabs on Wayland, causing shortcuts to stop working. Replaced toggle guard with a simple existence guard that prevents re-triggering while any picker window exists.
