Review Task Model

审核任务模型 - 支持过程中审核和生成后审核两种模式

## 审核模式说明

### 1. 过程中审核 (Process Review)
- 触发时机：Agent在流式输出过程中自主识别需要审核的内容
- 阻塞方式：阻塞式等待用户确认
- 消失方式：用户确认后自动销毁，不需要留存记录
- 交互位置：在聊天界面完成

### 2. 生成后审核 (Post-Creation Review)
- 触发时机：剧集生成完成后自动检查
- 触发源：根据用户配置的审核规则/Skill
- 阈值判断：根据阈值判断是否报告问题
- 存留方式：留存记录，用户可以确认问题、忽略问题、修改内容
