Cross-Platform Support Release

New Features

• Full Cross-Platform Compatibility: Now supports Unix/Linux, macOS, and Windows
• Platform Abstraction Layer: Clean architecture with proper class separation and specialization
• Windows Experimental Support: Basic Windows compatibility with appropriate warnings
• Platform-Aware Directory Handling:
  • Linux/macOS: ~/.local/share/dosctl/
  • Windows: %LOCALAPPDATA%/dosctl/

Technical Improvements

• Implemented abstract base classes for platform abstraction
• Added Factory pattern for automatic platform detection
• Created DOSBox launcher abstraction layer
• Windows subprocess optimizations (console window suppression)
• Maintained full backward compatibility

Windows Support Notice

Windows support is experimental and has not been extensively tested. Linux and macOS remain the primary supported platforms.

Architecture Changes

• New src/dosctl/lib/platform/ module with platform-specific implementations
• New src/dosctl/lib/dosbox/ module for DOSBox launcher abstraction
• Updated existing modules to use platform abstraction while preserving existing APIs

Compatibility

• All existing functionality preserved
• No breaking changes to existing commands or configuration
• Backward compatible directory access functions maintained

This release represents a significant architectural improvement while maintaining complete compatibility with existing installations.
