v0.8.0 — Phase β-7 App-Store-Vorbereitung

Feature-komplett für TestFlight. App-Icon-Platzhalter, Siri-Shortcut,
Share-Extension, Release-Checklist mit allen externen Apple-Schritten.

- scripts/make-appicon.swift: CoreGraphics-basierter Generator für
  1024×1024 forest-green PNG mit "C"-Letter und Karten-Stack-Schatten
- Asset-Catalog auf Single-Size-AppIcon-Pattern umgestellt
- StudyCardsIntent + CardsAppShortcuts (App Intents): Siri-
  Shortcut "Karten lernen mit Cards" / "Mit Cards lernen"
- CardsShareExtension Target: ShareViewController (UIKit-Bootstrap +
  SwiftUI-Hosting), ShareEditorView mit Text-Edit
- PendingShare + PendingShareStore shared in App-Group
  group.ev.mana.cards
- DeckListView zeigt PendingShare-Banner; Tap navigiert zu
  PendingShareConsumeView mit Deck-Picker + Front/Back-Felder, Submit
  → POST /cards, danach store.remove
- Info.plist: NSPhotoLibraryUsageDescription für Image-Occlusion-
  Picker, NSUserActivityTypes für Universal-Links
- docs/RELEASE_CHECKLIST.md mit externen Schritten: Apple-Developer-
  Portal, App-IDs, App-Group, AASA, Xcode-Archive, TestFlight-Plan,
  App-Store-Connect-Felder, Compliance-Verifikation
- UI-Test robuster (akzeptiert Login oder Decks/Entdecken als
  Launch-Erfolg, unabhängig vom Simulator-Keychain-State)
- 35 Tests + 1 UI-Test grün, alle drei Targets bauen

App-Store-Submission selbst ist externe Aktion und passiert nicht
durch dieses Repo — Schritte in docs/RELEASE_CHECKLIST.md.
