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
