feat: Add Reasoning Trace HUD Component
Closes #875

- Added new ReasoningTrace component for real-time reasoning visualization
- Shows agent's reasoning steps during complex task execution
- Supports step types: THINK, DECIDE, RECALL, PLAN, EXECUTE, VERIFY, DOUBT, MEMORY
- Includes confidence visualization, task tracking, and export functionality
- Integrated into existing GOFAI HUD system
