Add @MainActor to View, ViewModifier, Renderable, App, Scene protocols and all builders (ViewBuilder, SceneBuilder, ChildInfoProvider). Update renderToBuffer(), makeChildInfo(), resolveChildInfos() for main-actor isolation. Mark generic Equatable conformances with @preconcurrency. Update all 45 test suites with @MainActor annotation.
