Millian Lamiaux 99d8fba852 feat: 5 tab screens wired to centralized data layer
All tabs use shared data, stores, and SwiftUI islands:

- Home: greeting from userStore, featured/popular workouts,
  recent activity from activityStore, tappable collections
- Workouts: 50 workouts with SwiftUI Picker category filter,
  trainer avatars, workout grid, "See All" links to categories
- Activity: streak banner, SwiftUI Gauges (workouts/minutes/
  calories/best streak), weekly Chart, achievements grid
- Browse: featured collection hero, collection grid with emoji
  icons, programs carousel, new releases list
- Profile: user card, subscription banner, SwiftUI List with
  workout/notification settings (Switches persist via Zustand)

Tab layout uses NativeTabs with SF Symbols and haptic feedback.
