Initial commit: Industrial HMI system with component architecture

- Implement WebView2-based HMI frontend with React + TypeScript + Vite
- Add C# .NET backend with WebSocket communication layer
- Separate UI components into modular structure:
  * RecipePanel: Recipe selection and management
  * IOPanel: I/O monitoring and control (32 inputs/outputs)
  * MotionPanel: Servo control for X/Y/Z axes
  * CameraPanel: Vision system feed with HUD overlay
  * SettingsModal: System configuration management
- Create reusable UI components (CyberPanel, TechButton, PanelHeader)
- Implement dual-mode communication (WebView2 native + WebSocket fallback)
- Add 3D visualization with Three.js/React Three Fiber
- Fix JSON parsing bug in configuration save handler
- Include comprehensive .gitignore for .NET and Node.js projects
