Add Apple Watch companion app with complications and WCSession sync

- Add watchOS app target with mood voting UI (5 mood buttons)
- Add WidgetKit complications (circular, corner, inline, rectangular)
- Add WatchConnectivityManager for bidirectional sync between iOS and watch
- iOS app acts as central coordinator - all mood logging flows through MoodLogger
- Watch votes send to iPhone via WCSession, iPhone logs and notifies watch back
- Widget votes use openAppWhenRun=true to run MoodLogger in main app process
- Add #if !os(watchOS) guards to Mood.swift and Random.swift for compatibility
- Update SKStoreReviewController to AppStore.requestReview (iOS 18 deprecation fix)
- Watch reads user's moodImages preference from GroupUserDefaults for emoji style
