feat(web): 审稿改稿闭环——一键采纳/AI改写/正文高亮定位编辑/伏笔确认/草稿自动保存/章节目录

- 冲突「采纳改法」：有补丁瞬时改入终稿并选中；无补丁但可定位则采纳时调 AI（refiner）重写该段套入；定位不到提示手改
- 正文改为行内高亮叠层编辑器（与页面同底色、随内容增高、无滚动条），点冲突卡/锚点整页滚到并选中+闪烁
- 仅对可在正文定位的冲突显示「跳转」/锚点；locate 支持从 where 引号抽原文，杜绝定位失败刷屏
- 伏笔建议卡：新埋一键登记（预填表单）/ 疑似回收一键标记 CLOSED（复用现有端点）
- 审稿页草稿自动保存（防抖 PUT /draft），与「验收本章」解耦，刷新不丢
- 写作路由带章号 ?chapter=N + 验收成功面板/大纲页「写下一章」入口；写作目录从大纲列出全部章节
