/**
 * Release Workflow Script
 *
 * This script provides a comprehensive workflow for releasing a new version:
 * 1. Updates the version (major, minor, or patch)
 * 2. Automatically updates the CHANGELOG.md with commit messages since the last release
 * 3. Creates a GitHub release
 * 4. Deploys to NPM
 *
 * Usage:
 *   node scripts/release-workflow.js [patch|minor|major]
 *
 * If no version type is specified, it defaults to "patch"
