/**
 * Patch script to fix ESM/CJS interop issue with string-width in @inquirer/core.
 *
 * @inquirer/core bundles wrap-ansi@6 (CJS) which requires string-width@4 (CJS).
 * However, the top-level string-width is v8 (ESM-only), causing:
 *   ERROR stringWidth is not a function
 *
 * This script installs CJS-compatible versions of string-width and its
 * dependencies into @inquirer/core's nested node_modules after each install.
