+ * We use a separate bin file (instead of pointing directly to src/index.js)
+ * because TypeScript build processes don't preserve file permissions.
+ * By tracking this file in git with executable permissions (+x), we ensure
+ * the CLI remains executable after npm publish without needing post-install scripts.
