feat: riscrivi app in Flutter
Riscrittura completa da Vue 3 + Capacitor a Flutter/Dart. Architettura feature-based (lib/features/): - meal_planner: modello MealPlan/DayPlan, provider, pagina e widget - converter: modello ConversionEntry, provider con ricerca, pagina - shopping_list: modello ShoppingItem, provider con deduplicazione, pagina e widget Core: - Material 3 con seed color #2d6a4f - NavigationBar + IndexedStack (preserva stato dei tab) - Portrait lock via SystemChrome - Persistenza con shared_preferences - 50+ alimenti × metodi cottura in assets/data/conversions.json Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
