写作工作台重构剩余 3 项（多 agent 并行构建各自新文件，主线统一集成）： - WFW-5 内容感知书名（#6）：buildManuscriptExcerpt 取正文首尾摘录（硬上界控 token）； GeneratorRunner 加 manuscriptText，有 brief 字段时出现「用当前正文」按钮把摘录填入 brief，让 book-title 等据正文反推。纯前端零后端；HITL——只填表单，生成仍需作者触发。 - WFW-6 上下文速查抽屉（#7）：ContextDrawer 视口无关右侧 slide-over，设定库/大纲完整 只读速查 + 伏笔/规则/文风摘要跳链；底栏「速查」按钮触发。加法式、CONTEXT_DRAWER_ENABLED 一键回滚、旧侧栏/全宽页路由全保留。 - WFW-7 genre 采集 + 无大纲降级：项目无题材时首次写章前弹 GenrePicker 采集（临时并入 本次 directive 不落库）；chapters 为空时编辑器显式提示「尚无大纲，将按设定自由生成」。 各项 TDD：manuscriptExcerpt/useGenreGate/contextDrawer/useContextDrawer 共 32 新单测。 门禁全绿：vitest 629 / tsc / lint / build / coverage 95.43%。
