Refactor state machine for improved performance and maintainability

[sr-857]

Description

Optimize state machine implementation in src/state_machine/ for better performance.

Current Issues

• Complex state transitions
• Slow state persistence
• Difficult to test and debug

Tasks

• Simplify state transition logic
• Implement state caching
• Add state machine visualization
• Optimize state persistence
• Create comprehensive state machine tests
• Add state transition metrics

Acceptance Criteria

• State transition <10ms
• 100% test coverage
• State machine diagram generated
• State persistence optimized (90% faster)
• Clear error messages for invalid transitions

Improvements

• Use enum for states
• Implement state pattern
• Add transition guards
• Create state history tracking
