/**
 * 恢复被误删的作息日程（一次性数据恢复脚本）
 *
 * 背景：调试脚本的"清理"步骤误删了用户真实创建的日程。
 * 作息日程的删除是**软删除**（schedules.deleted = 1），数据行与 items_json 都还在，
 * 因此可直接把 deleted 改回 0 完成恢复，无需重建。
 *
 * 用法：
 *   node dev_test_scripts/debug/tool_restore_deleted_schedule.js            # 列出所有已软删的日程
 *   node dev_test_scripts/debug/tool_restore_deleted_schedule.js <scheduleId>  # 恢复指定 id
