test: 接入 jsdom 测试栈, 把 15 个 React hooks 纳入 80% 覆盖率门禁

新增 jsdom + @testing-library/react, 为 lib/** 全部 use*.ts hooks 写 renderHook 单测:
生成/CRUD(world/character/generator/outline/accept/foreshadow/rules)、
SSE流(draftStream/reviewStream)、定时轮询(autosave/jobPoll/kimiOauth)、
文风与注入(refine/styleLearn/injection)。覆盖率 mock api 客户端+Toast, 不打真实 LLM。
vitest.config.ts 去掉 use*.ts 排除; 前端覆盖率 63%→95%。CLAUDE.md 同步说明。
