[avivkeller]

• --dry-run (Run w/o creating any notes or issues)
• --verbose (Run w/ verbose Octokit)

[Copilot]

Pull Request Overview

This PR adds CLI support for dry-run and verbose modes to the meeting artifacts creation tool using Commander.js. It enables users to preview what would be created without making actual changes and provides detailed debug output.

Key changes:

• Refactored configuration system to support CLI options alongside environment variables
• Added dry-run mode that prevents actual creation of GitHub issues and HackMD documents
• Integrated verbose logging for GitHub API operations
