#### Code Structure:
```go
type GUIEnvironment struct {
    DisplayServer    string  // "x11", "wayland", "windows", "darwin"
    DesktopEnvironment string  // "gnome", "kde", "xfce", "windows11", "macos"
    ScaleFactor      float64 // Display scaling factor
    PrimaryMonitor   MonitorInfo
    HasCompositing  bool
    GPUInfo         GPUInfo
}

func DetectGUIEnvironment() GUIEnvironment
func (env GUIEnvironment) GetOptimalWindowSize(minWidth, minHeight int) fyne.Size
func (env GUIEnvironment) GetModuleSpecificSize(moduleID string) fyne.Size
```

### 4. Enhanced Main Application
**File**: `main.go`

#### Integration Features:
- **GUI Environment Integration**: Uses new detection system
- **Adaptive Window Sizing**: Intelligent window dimension selection
- **Platform Logging**: Detailed environment detection logging
- **Responsive Layout**: Module-specific size optimization

#### Code Integration:
```go
// Enhanced cross-platform GUI detection and window sizing
guiEnv := guitutils.DetectGUIEnvironment()
logging.Debug(logging.CatUI, "detected GUI environment: %s", guiEnv.String())

// Adaptive window sizing
optimalSize := guiEnv.GetOptimalWindowSize(800, 600)
w.Resize(optimalSize)
```

### 5. Comprehensive Testing Framework
**File**: `scripts/test-cross-platform.sh`

#### Test Capabilities:
- **Platform-Specific Testing**: Arch Linux and Windows 11 validation
- **GUI Detection Testing**: Code compilation and functionality
- **Installation Script Testing**: Enhanced feature verification
- **Dependency Validation**: Core component testing

#### Test Functions:
```bash
test_arch_linux()      # Arch Linux support validation
test_windows_11()       # Windows 11 support validation  
test_gui_detection()     # GUI environment testing
test_install_scripts()    # Installation script validation
