/**
* 图书元数据反查：按 书名 + 作者 + 年份 + 版次 检索 ISBN / 出版社 / 出版年。
*
* 背景：绝大多数图书参考文献既没有 DOI（拿不到 Crossref 的 ISBN 数组），
* 原文里也不会写 ISBN，所以只靠"抽取"永远拿不到，必须按书目信息去反查。
*
* 数据源：
* - Open Library（主源，免密钥可直连）：先检索 work，再拉 editions 按年份/版次/出版社挑具体版本
* - Google Books（备源，需 .env 配 google_books_api_key，无密钥时该 IP 会被 429）
*
* 环境变量：
* - book_isbn_lookup 0 关闭反查，默认开启
* - book_lookup_timeout 单次请求超时秒数，默认 8
* - google_books_api_key 配置后启用 Google Books 备源
