🔧 Implement robust cleanup system for Chromium process management

Major fixes for browser automation resource management:

- Chromium processes accumulating over time during automated trading
- Resource consumption growing after extended automation cycles
- Incomplete cleanup during analysis operations

 New Components:
- lib/enhanced-screenshot-robust.ts: Screenshot service with guaranteed cleanup
- lib/automated-cleanup-service.ts: Background process monitoring
- lib/auto-trading-service.ts: Comprehensive trading automation
- ROBUST_CLEANUP_IMPLEMENTATION.md: Complete documentation

- Finally blocks guarantee cleanup execution even during errors
- Active session tracking prevents orphaned browser instances
- Multiple kill strategies (graceful → force → process cleanup)
- Timeout protection prevents hanging cleanup operations
- Background monitoring every 30s catches missed processes

- lib/aggressive-cleanup.ts: Improved with multiple cleanup strategies
- app/api/enhanced-screenshot/route.js: Added finally block guarantees
- lib/automation-service.ts: Updated for integration

- validate-robust-cleanup.js: Implementation validation
- test-robust-cleanup.js: Comprehensive cleanup testing

The Chromium process accumulation issue is now resolved with guaranteed cleanup!
