Pull Request Overview

This PR removes unused commands and logic while refactoring the codebase for better maintainability. It eliminates the scan:sbom, report:purls, and report:committers commands along with their associated service logic, while consolidating and simplifying the EOL scanning functionality.

• Removes three unused CLI commands and their supporting infrastructure
• Refactors file operations, display formatting, and API client code into focused service modules
• Consolidates SBOM generation and EOL scanning logic with improved error handling
