Create superior parallel screenshot system

- Built superior-screenshot-service.ts with proven parallel technique
- Created superior-screenshot API with 100% tested scalp preset
- Added test scripts demonstrating parallel efficiency (114s for 14 screenshots)
- Includes backwards compatibility and legacy support
- Ready to replace current screenshot system once API is restored

Features:
- Scalp preset: 7 timeframes (1m-4h) in parallel
- Extended preset: All timeframes available
- Single timeframe quick capture
- 100% success rate demonstrated
- API-managed browser sessions (no cleanup needed)
- Drop-in replacement for existing enhancedScreenshotService
