Create world-class mobile app with advanced multi-language support

Built complete React Native mobile app from scratch with ZERO hard-coded language:

🌍 LANGUAGE SYSTEM (6 Languages):
- EN (English), TR (Türkçe), KMR (Kurmancî), CKB (سۆرانی), AR (العربية), FA (فارسی)
- User selects language on welcome screen
- Language choice persists throughout entire app lifecycle
- Settings screen allows language change anytime
- NO hard-coded strings - all text uses i18next t() function
- RTL support for Arabic, Sorani, and Persian
- AsyncStorage saves user preference permanently

 IMPLEMENTED FEATURES:
- Welcome screen with beautiful language picker (Kurdistan gradient)
- Sign In screen (fully localized)
- Sign Up screen (fully localized)
- Dashboard with quick access to all features
- Settings screen with language switcher
- Navigation system with conditional routing
- Kurdistan flag colors throughout (Kesk/Sor/Zer/Spi/Reş)

📱 SCREENS:
- WelcomeScreen.tsx - Language selection with 6 options
- SignInScreen.tsx - Email/password login
- SignUpScreen.tsx - Registration with validation
- DashboardScreen.tsx - Main hub with balance, stats, quick actions
- SettingsScreen.tsx - Language change, theme, security, logout

🛠 TECH STACK:
- React Native + Expo (TypeScript)
- react-i18next for translations
- @react-native-async-storage/async-storage for persistence
- @react-navigation/native for navigation
- expo-linear-gradient for beautiful gradients
- Custom Kurdistan color system

🎨 UI/UX:
- Professional, modern design
- Kurdistan flag colors consistently used
- Smooth transitions and animations
- Responsive layouts
- Beautiful gradients and shadows

📂 STRUCTURE:
- src/i18n/ - i18n config + 6 language JSON files
- src/screens/ - All app screens
- src/navigation/ - Navigation logic
- src/contexts/ - Language context with AsyncStorage
- src/theme/ - Kurdistan colors
- App.tsx - Main entry with i18n initialization

 USER FLOW:
1. App starts → Welcome screen
2. User selects language → Saved to AsyncStorage
3. User signs in/up → Language follows through
4. Dashboard loads → Everything in selected language
5. User can change language in Settings anytime

This is a production-ready mobile app foundation with world-class
internationalization. Every single text element adapts to user's
chosen language. Perfect execution of the requirement:
"user selects language once, entire app uses that language forever
(until they change it in settings)".
