/**
 * Generate Version Script
 *
 * This script generates a version.js file that exports the version from package.json.
 * This allows the CLI to access the version without having to read package.json directly,
 * which can be problematic when the package is installed globally.
 *
 * It also updates the version in the README.md file and CLI package.json to ensure they
 * stay in sync with the main package.json.
