 * 版本化发布：递增版本号 → 同步 manifest.json / package.json / updates.xml →

 *
 * 用法：
 *   npm run release -- patch              1.0.0 → 1.0.1
 *   npm run release -- minor              1.0.0 → 1.1.0
 *   npm run release -- major              1.0.0 → 2.0.0
 *   npm run release -- 1.4.0              指定版本
 *   npm run release -- patch --codebase http://host/auto-login.crx   同步自托管更新地址
