feat: capitalize all log messages for better readability

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.
