SwiftUI-UIKit Interop

Bridge UIKit and SwiftUI in both directions. Wrap UIKit views and view controllers for use in SwiftUI, embed SwiftUI views inside UIKit screens, and synchronize state across the boundary. Targets iOS 26+ with Swift 6.3 patterns; notes backward-compatible to iOS 16 unless stated otherwise.

See references/representable-recipes.md for complete wrapping recipes and references/hosting-migration.md for UIKit-to-SwiftUI migration patterns.
