feat: improve app ui and project metadata

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。

+### Definition of Done (每次编码完成的硬门禁) — 不通过不算完成
+
+每一次代码改动（无论多小）在声明「完成」前，**必须**按顺序全部通过以下门禁。任一项失败就回去修，不得跳过、不得只跑部分、不得仅靠肉眼判断。
+
+1. **TDD 已遵守** — 先写失败测试（RED）→ 实现到通过（GREEN）→ 重构（REFACTOR）。新增/修改的逻辑都有对应测试；改 bug 先写能复现的失败测试。见上文 §TDD。
+2. **测试覆盖率 ≥ 80%（已工具化 + CI 强制）** — 改动涉及的模块覆盖率不得低于 80%；新代码不许拉低整体覆盖率。跑命令核对真实数字，不要估：
+   - 后端：`uv run pytest -q --cov --cov-report=term-missing --cov-fail-under=80`（低于 80% 直接非零退出。当前基线 ~88%）。配置在根 `pyproject.toml` 的 `[tool.coverage.*]`。
+   - 前端：`cd apps/web && pnpm test:coverage`（`vitest.config.ts` 设 lines/functions/branches/statements 阈值 80。当前基线 ~95%）。
+   - **前端覆盖率范围 = `lib/**`（纯逻辑 + React hooks）**：hooks(`use*.ts`)用 jsdom + `@testing-library/react` 的 `renderHook` 单测（测试文件首行 `// @vitest-environment jsdom`，mock `@/lib/api/client` + `@/components/Toast`，参见 `lib/generation/useWorldGen.test.ts`）。组件(.tsx)仍由 E2E/人工验收覆盖，不在 vitest 范围（写新 hook 时必须同步补 `renderHook` 测试）。
+3. **跑完三类自动化测试**（改动触及的那侧必跑，跨栈改动两侧都跑）：
+   - **后端 Unit + Integration**：`uv run pytest -q`（需要 pg 的集成测试先 `docker compose up -d pg`）。
+   - **前端自动化测试**：`cd apps/web && pnpm test`（vitest）。
+   - **E2E**（动到 write→review→accept 主链路时）：跑相关 E2E 流程（mock gateway）。
+   - LLM 一律 mock，**绝不在测试/CI 命中真实 LLAPI**（见上文 §TDD）。
+4. **全部门禁绿**（与 §Toolchain、CI 一致）：
+   - 后端：`uv run ruff check .` · `uv run ruff format .` · `uv run mypy packages apps` · `uv run pytest -q` · 动过模型时 `uv run alembic check` 无漂移。
+   - 前端：`cd apps/web && pnpm lint` · `pnpm typecheck` · `pnpm test` · `pnpm build`；动过后端 schema 先 `pnpm gen:api` 再校验。
+5. **符合架构与编程规范** — 不违反上文 §Architectural invariants、§Locked tech stack、§Python/§Frontend/§LangGraph 实践，以及全局编码风格（不可变更新、KISS/DRY/YAGNI、文件 <800 行、函数 <50 行、显式错误处理、边界校验、无硬编码密钥）。安全敏感改动（auth/输入处理/DB 查询/外部 API/加密）按 §code-review 触发安全自查。
+6. **提交（每次完成都 commit）** — 见下文 §Commit discipline。
+7. **回写状态/文档** — 按 §Per-task workflow 更新 `PROGRESS.md`；若实现暴露 spec 缺口，回写对应 spec（见 §Conventions）。
+
+> 报告要诚实：测试失败就如实说明并贴输出；跳过了哪一步要讲明；只有真正跑过且全绿，才说「完成」。
+
+### Commit discipline (提交纪律) — 每次完成即提交
+
+- **每次完成一个可工作的改动就 commit**，小步提交、一次一个聚焦改动；不要把多个无关改动堆进一个提交。
+- **提交前** Definition of Done 的门禁（1–5）必须已全绿——不提交跑不过测试或 lint/类型不干净的代码。
+- **提交信息格式**：遵循 Conventional Commits —— `<type>: <description>`（type ∈ feat/fix/refactor/docs/test/chore/perf/ci），中文描述与本仓库现有提交风格一致；需要时附 body 说明「为什么」。
+- **提交信息禁止任何署名/归属尾注** — **不得包含 `Co-Authored-By:` 或任何 `Generated with` / AI 署名行**（全局已在 `~/.claude/settings.json` 关闭 attribution；此处再次明确，覆盖任何默认加尾注的行为）。
+- **分支**：不在 `main` 上直接提交；按 §Git Workflow 在特性分支工作。`develop` 为当前集成分支。
+- **push / 开 PR 仅在用户明确要求时**进行；PR body 同样不加 AI 署名。

+| CR-M3 🟡 LangGraph 链健壮性 | ⬜ | @llm | — | `chain_runner.py:124` accept commit 后 `run_overdue_scan` 非幂等且失败无法 resume→部分进度空洞（幂等化或纳入事务）；`chain_runner.py:159` 改用公开 `get_state().next` 替私有 `__interrupt__`；`chain/nodes.py:213` 链内 4 审串行→并行/复用 review 子图 |
+| CR-M4 🟡 前端 key/a11y/cleanup 批 | ⬜ | @frontend | — | 可编辑列表去 index-key（`CharacterGenerator.tsx:135`/`GeneratorRunner.tsx:178`/`ForeshadowCard.tsx:68`）；SSE `KNOWN_EVENTS` 补 `stop`（核对 `memory/contracts.md`）；ARIA 补全（AppShell nav label / NavDrawer aria-controls / ForeshadowCard `<dl>` 结构）；ProjectWizard 步骤焦点；`ReviewReport.tsx:301` setTimeout 卸载清理 |
