Capitalize the first letter of all log messages throughout the codebase to improve readability and consistency in logging output. Key improvements: - All log messages now start with capital letters - Consistent formatting across all logging statements - Improved readability for debugging and monitoring - Enhanced user experience with better formatted messages Files updated: - CLI commands and service management - Internal client information discovery - Network operations and configuration - DNS resolver and proxy operations - Platform-specific implementations This completes the final phase of the logging improvement project, ensuring all log messages follow consistent capitalization standards for better readability and professional appearance.
