alexpaynex cf1819f34b feat(mobile): scaffold Expo mobile app for Timmy with Face/Matrix/Feed tabs
Task #42 — Timmy Harness: Expo Mobile App

## What was built
- New Expo artifact at artifacts/mobile, slug `mobile`, preview path `/mobile/`
- Three-tab bottom navigation (Face, Matrix, Feed) — NativeTabs with liquid glass on iOS 26+
- Dark wizard theme (#0A0A12 background, #7C3AED accent)

## WebSocket context (context/TimmyContext.tsx)
- Full WebSocket connection to /api/ws with exponential backoff reconnect (1s→30s cap)
- Sends visitor_enter handshake on connect, handles ping/pong
- Derives timmyMood from agent_state events (idle/thinking/working/speaking)
- recentEvents list capped at 100
- sendVisitorMessage() sets mood to "thinking" immediately on send (deterministic waiting state)
- speaking mood auto-reverts after estimated TTS duration

## Face tab (app/(tabs)/index.tsx)
- Animated 2D wizard face via react-native-svg (hat, head, beard, eyes, pupils, mouth arc, magic orb)
- AnimatedPupils: pupilScaleAnim drives actual rendered pupil Circle radius (BASE_PUPIL_R * scale)
- AnimatedEyelids: eyeScaleYAnim drives top eyelid overlay via Animated.Value listener
- AnimatedMouth: smileAnim + mouthOscAnim combined; SVG Path rebuilt on each frame via listener
- speaking mood: 1Hz mouth oscillation via Animated.loop; per-mood body bob speed/amplitude
- @react-native-voice/voice installed and statically imported; Voice.onSpeechResults wired properly
- startMicPulse/stopMicPulse declared before native voice useEffect (correct hook order)
- Web Speech API typed with SpeechRecognitionWindow local interface (zero `any` casts)
- sendVisitorMessage() called on final transcript (also triggers thinking mood immediately)
- expo-speech TTS speaks Timmy's chat replies on native

## Matrix tab (app/(tabs)/matrix.tsx)
- URL normalization: strips existing protocol, uses http for localhost, https for all other hosts
- Full-screen WebView with loading spinner and error/retry state; iframe fallback for web

## Feed tab (app/(tabs)/feed.tsx)
- FlatList<WsEvent> with proper generics; EventConfig discriminated union (Feather|MaterialCommunityIcons)
- Icon names typed via React.ComponentProps["name"] (no `any`)
- Color-coded events; event count in header; empty state with connection-aware message

## Type safety
- TypeScript typecheck passes with 0 errors
- No `any` casts anywhere in new code

## Deviations
- expo-av removed (not used; voice input handled via @react-native-voice/voice + Web Speech API)
- expo-speech/expo-av NOT in app.json plugins (no config plugins — causes PluginError if listed)
- app.json extra.apiDomain added for env-driven domain configuration per requirement
- expo-speech pinned ~14.0.8, react-native-webview 13.15.0 for Expo SDK 54 compat
- artifact.toml ensurePreviewReachable removed (Expo uses expo-domain router)
- @react-native-voice/voice works in Expo Go Android; iOS needs native build (graceful fallback)
