* 【修复 #8】批量清理命令处理函数（优化并发性能）
|

*
|
||
* 功能说明：
|
||
* 1. 检查所有用户的话题记录
|
||
* 2. 找出话题ID已不存在（被删除）的用户
|
||
* 3. 删除这些用户的KV存储记录和验证状态
|
||
* 4. 让他们下次发消息时重新验证并创建新话题
|

*
|
||
* 使用场景：
|
||
* - 管理员手动删除了多个用户话题后
|
||
* - 需要批量重置这些用户的状态
|
||
*
|
||
* @param {number} threadId - 当前话题ID（通常在General话题中调用）
|
||
* @param {object} env - 环境变量对象
