PlasmaZones 2.1.0

Breaking Changes

• Assignment storage migrated from JSON to KConfig: Per-screen layout assignments (snapping layout and tiling algorithm) are now stored in plasmazonesrc KConfig groups ([Assignment:*]) instead of assignments.json. Existing assignments.json files are automatically migrated on first startup and renamed to assignments.json.migrated.

Added

• Per-desktop/activity tiling state isolation (fixes #212): Each virtual desktop and activity now maintains independent tiling state (window membership, master count, split ratios, floating state). Switching desktops no longer interferes with tiling on other desktops.
• Zone shaders: Added Fedora Drift, NixOS Drift, openSUSE Drift, and KDE Neon gear zone shaders

Fixed

• Editor: new zones could not reach canvas edges during drag (fixes #215): Grid-aligned snap clamping prevented zones from reaching canvas boundaries, and gap calculation used stale data during drag operations
• Login freeze from startup OSD: Prevented OSD from blocking the D-Bus event loop during daemon startup

Changed

• KCM refactored into sub-KCMs: Split into Layouts, Snapping, Tiling, Shortcuts, Apps & Windows, and About sub-modules with a shared common library
