+/**
+ * 时间字段批量转换工具（v1.0.16）
+ * 需求：mysuperlink 数据库所有数据表的时间字段调整为"年-月-日"（DATETIME/TIMESTAMP -> DATE）。
+ * 用法：php tools/migrate_time_to_date.php [库名]
+ * 说明：
+ *   - 自动遍历指定库（默认取 config/database.php 的 dbname）中所有 DATETIME/TIMESTAMP 字段，
+ *     生成并执行 ALTER TABLE ... MODIFY ... DATE。
+ *   - 对带默认值 CURRENT_TIMESTAMP 的字段，改为 DEFAULT (CURRENT_DATE)（需 MySQL 8.0.13+）；
+ *     若执行环境为 MySQL 5.7，请手动调整或保留 DATETIME。
+ *   - 已存在 DATE 类型的字段不会重复处理；脚本幂等，可重复执行。
