0.3.1

Fixed

• ThemeKitSwiftUI.ThemeApplier renders the default variant's color scheme for the current system scheme until a value is persisted, so a first launch no longer renders its first frame in fallback.colorScheme and then flips, which could leave macOS window titles and sidebar text resolved for the wrong appearance
• ThemeKitSwiftUI.ThemeApplier applies the stored default variant's color scheme on first appear instead of relying on onChange(of:), which did not fire when that value equalled fallback and left NSApplication.shared.appearance / UIWindow.overrideUserInterfaceStyle unset for the first session
• ThemeKitUIKit.ThemeApplier sets the window's overrideUserInterfaceStyle for the stored default variant on first appear, instead of leaving it unset until the theme next changed, because theme observation starts after onAppear()
