Refactor UnifiedCoordinator to follow Single Responsibility Principle

- Create dedicated service classes for separated concerns:
  * AgentService: Agent management and health monitoring
  * WorkflowService: Workflow parsing and execution tracking
  * PerformanceService: Metrics and load balancing
  * BackgroundService: Background processes and cleanup
  * TaskService: Database persistence (already existed)

- Refactor UnifiedCoordinator into UnifiedCoordinatorRefactored
  * Clean separation of responsibilities
  * Improved maintainability and testability
  * Dependency injection pattern for services
  * Clear service boundaries and interfaces

- Maintain backward compatibility through re-exports
- Update main.py to use refactored coordinator
