节点以及工作流执行历史是否会定时删除？

Coze部署一周后，MySQL的数据大小有点超出预期。查看数据表大小后，发现`node_execution`这张表数据量比较大。

请问是否有删除指定天数前的节点执行历史的配置方式？

The issue mentions MySQL and the node_execution table but names no source file, test, or entry point. Start by locating the code that stores node and workflow execution history, then trace any existing retention or cleanup configuration. Done would require a documented, tested way to remove history older than a specified number of days.
