- Add NSUbiquitousKeyValueStore entitlement to KisaniCal.entitlements
- New CloudSyncManager: mirrors UserDefaults to iCloud KV Store on every save; restores to UserDefaults on fresh install when local data is missing; observes external changes to pull updates in real-time; guards against 1 MB limit
- TaskViewModel: restore from iCloud on init, push to iCloud on every save
- WorkoutViewModel: restore programs/schedule/activePid/completedDates from iCloud on init, push all four keys on every save
- ContentView: restoreSettings() + backupSettings() on appear and foreground — syncs ~18 small settings keys (appearance, tabs, tutorial flags, calendar prefs, workout notifications)
