v0.7.0 — Phase β-6 Native-Polish

Drei Sub-Pakete: Keyboard-Shortcuts, Daily-Reminder-Notifications,
WidgetKit-Extension mit App-Group-Daten-Sharing. Siri-Shortcuts
und Share-Extension auf β-7 verschoben — niedrige Priorität, die
drei großen Brocken decken 90% des Native-Polish ab.

Keyboard-Shortcuts:
- Hidden Buttons in StudySessionView mit .keyboardShortcut
- Space = flip, 1/2/3/4 = again/hard/good/easy
- iPad-Magic-Keyboard + macOS-tauglich

Daily-Reminders:
- NotificationManager @Observable mit UNUserNotificationCenter
- Authorization-State + Permission-Request-Flow
- UNCalendarNotificationTrigger täglich zur konfigurierten Zeit
- SettingsView in AccountView mit Toggle + DatePicker
- UserDefaults-Persistierung von Hour/Minute/Enabled

WidgetKit-Extension:
- WidgetSnapshot Codable mit topDecks (Top-3 by dueCount) + totalDueCount
- WidgetSnapshotStore schreibt in group.ev.mana.cards-Container
- DeckListStore.refresh schreibt Snapshot + WidgetCenter.reloadAllTimelines
- CardsWidgetExtension-Target im project.yml (app-extension)
- CardsWidgetBundle + CardsDueWidget mit 5 Familien (small/medium/
  accessoryCircular/accessoryInline/accessoryRectangular)
- DueProvider TimelineProvider mit 30-min-Refresh
- DueWidgetView Family-Switch
- WidgetSnapshot.swift shared in beiden Targets via XcodeGen sources
- App-Group im Haupt- und Widget-Entitlement

35 Tests grün (keine neuen Tests in β-6 — WidgetKit + Notifications
sind System-API-Integrationen, Tests wären überwiegend Mocks).
Build inkl. Widget-Extension grün.
