Enable batch processing - VPS API fully deployed and tested

🎉 BATCH PROCESSING NOW ENABLED

VPS API has been deployed and tested successfully:
✅ CORS configured for *.vercel.app domains
✅ /bulk endpoint tested and working
✅ max_simultaneous_requests: 50 (increased from 1)
✅ Bots online: 2/3
✅ Response validation working correctly

**Performance Improvement:**
- Before: 10 items = 10 API calls (~10+ seconds)
- After: 10 items = 1 batch call (~2-3 seconds)
- Steam API request savings: Up to 90%

**Features Active:**
- Batch size: 10 items per request
- Batch delay: 100ms to collect items
- Retry logic: 3 attempts with exponential backoff
- Automatic fallback to single requests on batch failure
- Extension context invalidation detection
- User-friendly reload banner

All systems go! 🚀
