phosphor-zones

Manual zone data model, registry, and ILayoutSource.

The heart of the manual-tiling model. Zone is a UUID-keyed rect with metadata; Layout is a collection of zones plus per-context (screen/desktop/activity) assignment rules. ZoneDetector resolves cursor-to-zone. LayoutRegistry is the concrete catalogue + assignment store implementing both IZoneLayoutRegistry and the ILayoutSourceRegistry provider contract; ZonesLayoutSource publishes manual layouts to the rest of the stack via ILayoutSource. JSON persistence uses normalised 0..1 coordinates so the same layout works on any screen size.
