This commit extends the documentation effort by adding detailed explanatory comments to key CLI components and core functionality throughout the cmd/ directory. The changes focus on explaining WHY certain logic is needed, not just WHAT the code does, improving code maintainability and helping developers understand complex business decisions. Key improvements: - Main entry points: Document CLI initialization, logging setup, and cache configuration with reasoning for design decisions - DNS proxy core: Explain DNS proxy constants, data structures, and core processing pipeline for handling DNS queries - Service management: Document service command structure, configuration patterns, and platform-specific service handling - Logging infrastructure: Explain log buffer management, level encoders, and log formatting decisions for different use cases - Metrics and monitoring: Document Prometheus metrics structure, HTTP endpoints, and conditional metric collection for performance - Network handling: Explain Linux-specific network interface filtering, virtual interface detection, and DNS configuration management - Hostname validation: Document RFC1123 compliance and DNS naming standards for system compatibility - Mobile integration: Explain HTTP retry logic, fallback mechanisms, and mobile platform integration patterns - Connection management: Document connection wrapper design to prevent log pollution during process lifecycle Technical details: - Added explanatory comments to 11 additional files in cmd/cli/ - Maintained consistent documentation style and format - Preserved all existing functionality while improving code clarity - Enhanced understanding of complex business logic and platform-specific behavior These comments help future developers understand the reasoning behind complex decisions, making the codebase more maintainable and reducing the risk of incorrect modifications during maintenance.
