Add @State, StateBox, Binding, DependencyTracker, and SubscriptionToken for targeted reactive updates. Label gains two reactive overloads: Label(Binding<String>) for the explicit-binding path and Label(() -> String) for tracked closures. Both update the Gtk.Label text in-place without re-mounting. Regression tests verify label updates survive when the Swift wrapper is deallocated after the GObject is attached to the widget tree (GTK does not retain wrappers). Includes 28 new tests across ReactiveLabelTests and StateTests suites.
