feat: implement safe area insets for Android and add development tooling

- Add @capacitor/status-bar dependency for safe area detection
- Implement SafeAreaPlugin for Android with proper inset calculation
- Create safeAreaInset.js utility for CSS custom property injection
- Update Android manifest and build configuration for plugin
- Integrate safe area handling across Vue components and views
- Update iOS Podfile and Android gradle configurations
- Add commitlint and husky for commit message validation

Technical changes:
- SafeAreaPlugin uses WindowInsets API for Android R+ devices
- Fallback detection for navigation bar and gesture bar heights
- CSS custom properties: --safe-area-inset-{top,bottom,left,right}
- Platform-specific detection (Android WebView only)
- StatusBar plugin integration for top inset calculation
