PlasmaZones 1.9.1

Added

• Snap Assist: Aero Snap style window picker after snapping, allowing users to fill empty zones with unsnapped windows (#95)
• Snap Assist overlay with window thumbnails, zone-mapped layout, and KCM setting to enable/disable
• getEmptyZonesJson and showSnapAssist D-Bus APIs for Snap Assist integration

Fixed

• Zone padding and outer gap in individual layout settings now persist correctly when saving (#145)
• Default layouts no longer include redundant zone padding override (use global setting by default)
• Snap Assist: overlay zone appearance matches zone colors and borders. Thumbnail caching across continuation
• Snap Assist: KWin effect default for snapAssistEnabled until D-Bus loaded (avoids race)

Changed

• Packaging: add env.d to RPM %files. Remove redundant Snap Assist message from Arch install
