2.1.0: app de Apple Watch, complicacion y widget semanal en iOS

- Target MealMoodWatch (watchOS 10, SwiftUI): vista de hoy y de la
  semana en TabView vertical; recibe el snapshot del iPhone por
  WatchConnectivity (updateApplicationContext) y lo guarda en su app
  group para la complicacion
- Target MealMoodWatchWidget: complicacion accessoryRectangular/
  Circular/Inline con las comidas de hoy (heuristica comida/cena por
  hora); icono del watch generado desde el logo
- WatchWeekPayload compartido entre iOS app, widget iOS, watch app y
  complicacion — llega ya localizado desde el iPhone
- Widget iOS nuevo "Semana" (systemMedium/Large) con los 7 dias;
  el widget de hoy pasa a WidgetBundle
- Targets creados via gema xcodeproj (sin abrir Xcode); embed del watch
  antes del script de Crashlytics para evitar ciclo de build
