v0.2.0 — Phase β-1 Decks lesen

Deck-Liste mit Web-Parität: alle eigenen Decks aus cardecky-api,
Card-/Due-Counts pro Deck (Web-Pattern: separate Calls), Pull-to-
Refresh, Offline-Read via SwiftData, Inbox-Banner für Marketplace-
Forks.

- Deck-Codable-DTO mit snake_case-CodingKeys (DeckCategory,
  DeckVisibility, FsrsSettings)
- ISO8601-Date-Decoder mit Fractional-Seconds-Toleranz
- CardsAPI.listDecks() + cardCount() + dueCount()
- CachedDeck SwiftData-Model mit lastFetchedAt
- DeckListStore (API + Cache, paralleles Counts-Fetching via TaskGroup)
- DeckListView mit forest-Theme, deck.color-Streifen, Inbox-Banner
- AccountView mit Sign-out
- DashboardView durch DeckListView ersetzt
- 6 Unit-Tests + 1 UI-Test grün
