ai-labeling: Prompt 1 v0.3(80%) + Prompt 3 v0.2(90%) + GT v0.4.2

Prompt 1 迭代 v0.1→v0.3：
- 多选字段加显著篇幅门槛+从属零件反例教学
- 前沿科技vs横切类比拆清（技术主角测试）
- 装备深解加同类体系/窄类别测试
- 跨域改为传播分类框（≥3域即标，非军事术语）
- 全对率 40%→80%

Prompt 3 开篇钩子 v0.1→v0.2：
- 阅读范围扩至3段（导视+主持人+首段解说）
- 强判定从紧迫感硬门槛改为6条独立路径
- 弱判定区分信息性提问vs悬念式提问
- 命中率 50%→90%

ground-truth v0.4.2：ep008补标跨域 + 20期opening_hook全标注
脚本：run_labeling/summarize 支持 opening_hook，summarize改从源GT读取
