Pull Request Overview

This PR introduces a centralized logging system to replace direct console.log, console.warn, console.error, and stdout.write calls throughout the codebase, enabling a quiet mode feature via a new --quiet / -q CLI flag.

• Adds a new Logger class with methods for different log levels (info, warn, error, debug, progress)
• Replaces all console.* calls and stdout.write with the new logger methods
• Adds quiet mode support via CLI flag that suppresses all output except errors
