/**
 * 将「当前选用的静态基址」写入 pages.json、index.html。
 * - 目标基址：`STATIC_ASSETS_BASE_URL` 环境变量，否则取 `static-assets-defaults.js` 中 **STATIC_ASSETS_BASE_URL_TEST**。
 * - 若文件中仍是更旧的 CDN 前缀，可一次性指定 `PREV_STATIC_ASSETS_BASE_URL`（要整段替换掉的前缀，须以 / 结尾），例如：
 *   `PREV_STATIC_ASSETS_BASE_URL=https://old-host/sqxp-static/ npm run sync-static-public-urls`
 *   不设则仅把「与目标相同」视为已就绪，不做无意义的替换。
 *
 * 生产发版：先设 `STATIC_ASSETS_BASE_URL` 为生产根地址再执行。
 * 用法：在 sqxp-wx 根目录执行 `npm run sync-static-public-urls`
