## Work on FRE-58: Energy System & Starter Pack IAP

### Accomplished Today

**IAP Integration Complete:**

1. **Created `hooks/useIap.ts`** - React hook for in-app purchases:
   - Auto-initializes IAP connection on mount
   - Loads product info from App Store/Play Store
   - Provides `purchaseProduct()` method with proper callback handling
   - Exposes real price, title, description from store
   - Handles connection state and errors

2. **Updated `app/(tabs)/dungeon/purchase.tsx`:**
   - Integrated real IAP flow instead of mock purchase
   - Shows actual store price dynamically (e.g., "$1.99" or "€1.99")
   - Added loading overlay while connecting to payment system
   - Purchase button shows "Processing..." during transaction
   - Only grants unlimited energy after successful purchase confirmation
   - Properly handles cancelled purchases without error alerts

3. **Updated `app/_layout.tsx`:**
   - Added IAP initialization in `RootLayoutNav` useEffect
   - Initializes alongside database and sync manager on user sign-in
   - Sets up event listeners for purchase updates
   - Gracefully handles init failures (will retry on demand)

### Technical Details

**Purchase Flow:**
```
User clicks "Buy Now"
    ↓
Show confirmation with real price from store
    ↓
Call purchaseProduct(PRODUCT_IDS.UNLIMITED_ENERGY_DAILY)
    ↓
react-native-iap opens native payment sheet
    ↓
User confirms payment in OS dialog
    ↓
purchaseUpdatedEvent fires → IAP service consumes purchase
    ↓
Hook callback resolves → grant unlimited energy via energyService
    ↓
Show success alert, navigate back
```

**Files Changed:**
- `hooks/useIap.ts` (new) - 129 lines
- `app/(tabs)/dungeon/purchase.tsx` - Updated purchase flow
- `app/_layout.tsx` - Added IAP initialization
