0.2.0

Added

• Per-screen chrome behavior — NativeBarConfig (hidesTopBar, hidesTabBar, per-screen
  actions) carried on NativeChromeEntry.bar, so any host can drive per-screen bar visibility and
  native toolbar actions through the existing chrome projection. Defaults unchanged; fully opt-in.
• iOS shell style registry — NativeShellStyle + applyNativeShellStyle() (iosMain): themed /
  system-material / custom bar backgrounds, global tint, tab-item selected/unselected colors, title
  font, and hairline visibility for the native UINavigationBar/UITabBar chrome, with
  nativeShell…UIColor resolvers for Swift shells.
• The sample app gained Compose-side bar slots + restylable defaults (NativeNavDefaults) and a
  "Navigation toolbar styles" catalog (Settings → Developer) demonstrating the full customization
  surface on both platforms, including documented limitations.
