Refactor: implement modular architecture for WfbngLink component

[vertexodessa]

This commit represents a major architectural refactoring that breaks down the monolithic WfbngLink class into specialized, focused components with clear separation of concerns. The refactoring improves code organization, maintainability, and thread safety while introducing a more modular design.

Key Architectural Changes

New Manager Classes:

• DeviceManager: RAII wrapper for RTL8812 device management with proper lifecycle management and thread safety
• AggregatorManager: Centralized management of network aggregation for video, mavlink, and UDP streams
• ThreadManager: Named thread lifecycle management with proper cleanup and thread safety
• AdaptiveLinkController: Dedicated component for adaptive link quality monitoring and control
• PacketProcessor: Specialized packet processing and routing with statistics management

Configuration & Logging:

• WfbConfiguration: Centralized configuration management consolidating all hardcoded values
• WfbLogger: Structured logging system with categories and levels for better debugging

Technical Improvements

• Thread Safety: Improved with proper mutex usage and RAII patterns
• Resource Management: Enhanced error handling and automatic cleanup
• Separation of Concerns: Dedicated components for specific functionality
• Maintainability: Configuration-driven architecture for easier customization
• Debugging: Structured logging system with categorized output

Files Changed

• Added: 15 new header and implementation files for modular components
• Modified: 5 existing files to integrate with new architecture
• Total: 20 files changed, 3084 insertions(+), 432 deletions(-)

Impact

This refactoring establishes a solid foundation for future development by providing:

• Better code organization and readability
• Improved testability through component isolation
• Enhanced error handling and debugging capabilities
• More flexible configuration management
• Thread-safe operations with proper resource management

The changes maintain backward compatibility while providing a more robust and maintainable codebase structure.
