/**
 * patch-deps.js — 统一修补 node_modules 依赖
 *
 * 解决 Vue 3 + Vite 项目中依赖兼容性问题。
 * 每次 npm install 后由 postinstall 自动执行，也可手动运行：
 *   node scripts/patch-deps.js
 *
 * 修补清单：
 *   1. xe-utils/hasOwnProp.js — Vue 3 Proxy 兼容
 *   2. element-plus form-label-wrap.mjs — NaN 防护 + 生命周期守卫
 *
 * 特性：幂等（safe to run multiple times）
