业务规则：
- 路径参数推荐始终传主问题 ID；兼容传入同一会话链内任一追问 ID，服务端都会按
root_question_id自动寻找 ID 最大的最新节点。 - 只能追问当前粉丝自己的会话链；最新节点必须为已回答状态，最新追问未回答时不能继续追问。
- 粉丝仍必须对该偶像存在有效订阅。
- 每次追问都是新的付费行为，追问价格取
tieup_business_config.basic.follow_up_question_candy，成功创建时独立扣减糖果。 - 追问同样写入
tieup_question，通过parent_question_id关联上一条已回答问题，通过root_question_id归属同一条问答链，糖果扣减使用business_type = follow_up_question。 - 同一会话链创建追问时会锁定主问题行并在事务内重查最新节点；并发请求不会从同一已回答节点创建两条分叉追问。
- 同一
Idempotency-Key只能复用同一会话链、同一追问内容和同一附件快照；换会话链、换内容或换附件会返回422，提示该幂等键已用于其他提问。
