bengizmo afc221a98a feat: Implement comprehensive enterprise monitoring and optimization infrastructure
Add complete enterprise-level reliability, security, and performance systems:

## Core Monitoring Systems
- **Health Monitor**: 8 automated health checks with email alerts and REST API
- **Error Recovery**: 4 recovery strategies (retry, fallback, circuit breaker, graceful failure)
- **Security Monitor**: Real-time threat detection with automatic IP blocking
- **Performance Monitor**: Performance tracking with automated benchmarks and alerts

## Data Protection & Optimization
- **Backup Manager**: Automated backups with encryption, compression, and disaster recovery
- **Cache Optimizer**: Intelligent caching with 3 strategies and 5 specialized cache groups

## Enterprise Features
- Automated scheduling with WordPress cron integration
- Admin dashboards for all systems under Tools menu
- REST API endpoints for external monitoring
- WP-CLI commands for automation and CI/CD
- Comprehensive documentation (docs/MONITORING-SYSTEMS.md)
- Emergency response systems with immediate email alerts
- Circuit breaker pattern for external service failures
- Smart cache warming and invalidation
- Database query caching and optimization
- File integrity monitoring
- Performance degradation detection

## Integration
- Plugin architecture updated with proper initialization
- Singleton pattern for all monitoring classes
- WordPress hooks and filters integration
- Background job processing system
- Comprehensive error handling and logging

Systems provide enterprise-grade reliability with automated threat response,
proactive performance monitoring, and complete disaster recovery capabilities.
