Fixed automation v2 start button (relative API URLs)
 Fixed batch analysis API endpoint in simple-automation
 Fixed AI learning storage with correct userId
 Implemented comprehensive learning data storage
 Fixed parallel analysis system working correctly

- Updated simple-automation to use localhost:3000 for batch analysis
- Fixed learning integration with 'default-user' instead of 'system'
- AI learning now stores analysis results with confidence/recommendations
- Batch analysis working: 35s completion, 85% confidence, learning stored
- True parallel screenshot system operational (6 screenshots when multi-timeframe)
