fix(ai-script): 深度档 repair 严格按自检逐条改(喂上一稿 + 强约束)

问题:verify 后的修订阶段,模型没严格按自检 issue 改 —— 根因是 repair 只给了大纲+问题提示、
没给上一稿,模型是'凭大纲重写'而非'在原稿上逐条改'。

- DeepWriteInput 加 prevDraft;strategy 的 repair(run + runStream)把上一稿传进去。
- buildWritePrompt repair 分支重写:① 附【上一稿(待修订)】②【必须修正的问题,逐条缺一不可,每条带'必须改成'】
  ③【修订铁律:只动被点名处/其余原样/不得引入新违规/缺一不可】。
- writeCall promptVersion → v11。
验证(本地深度生成触发 repair):repair invocation prompt 含上一稿+逐条问题+铁律(4项校验全 t)。
