feat: M4 文风 + M5 生成/多provider/Skill + Kimi Code 订阅接入 + 本地联调修复

M4（文风）: style-auditor 双轨（提取指纹/漂移第四审）+ jobs 长任务框架(zombie reaper) + 回炉 refine + GET /style read-back。
M5（生成+扩展）: worldbuilder/character-gen（入库 continuity 409 gate + partition_writes 白名单 + schema→JSONB 形变）；
  网关多 provider 回退链/熔断/能力降级（Anthropic/Gemini 适配器）；Skill registry + 表权限沙箱 + 规则；
  前端 角色生成器/世界观/Codex/规则页/技能库/⌘K 命令面板。
K1（Kimi Code 订阅接入）: OAuth device-flow（kimi-code）+ 静态 Console key（kimi-code-key）两路径；
  coding 端点 KimiCLI 伪造头（实测 UA allow-list 门禁，缺则 403）+ JSON 模式结构化（thinking ⊥ tool_choice）。
本地联调修复: CORS 中间件；assemble 注入 premise+「写第N章」指令（修空 prompt 400）；
  GET /outline·/draft read-back + 大纲/工作台/审稿页重载；写页 client/server 常量边界 + notFound 健壮化；
  字数 toLocaleString locale 水合；审稿页终稿从已存草稿 seed（修 accept 422）。
门禁: backend ruff/mypy(157)/alembic 无漂移/pytest 451 · frontend lint/tsc/vitest/build。

 ## Repository status
 
-**This is a spec-only repository at the pre-implementation stage.** There is no application code yet — only four design documents. The next step is Phase 0 / T0.1 in `DEV_PLAN.md` (scaffold the monorepo). Do not assume any build/test tooling exists until you create it.
+**Phase 0–5 (M1–M5) are all shipped; there is no active phase.** The monorepo is scaffolded and the full MVP loop runs end-to-end: 立项 → 设定库 → 大纲 → 写章(SSE) → 四审(一致性/伏笔/文风/节奏) → 验收事务，底层带多 provider 网关(路由/回退/熔断) + 声明式 skill 注册表(§5.5) + Kimi Code OAuth(K1)。Last green gate: backend ruff/format clean · mypy **154 files** · alembic **no drift** · pytest **434 passed**; frontend lint/typecheck clean · vitest **155 passed** · build OK. **The build/test tooling exists — see §Toolchain below; do not re-scaffold.**
+
+`PROGRESS.md` is the authoritative status ledger (current phase + archived M1–M5 detail + changelog). Read it before any task. **Next work if resumed**: DEV_PLAN §4 P2/后续 (向量检索 / 真任务队列 / 全书一致性扫描 / 社区市场), or the 对标竞品功能补齐 plan (`~/.claude/plans/streamed-giggling-fiddle.md` — AI续写/扩写、AI拆书、通用生成器框架、细纲、模板库).
 
 Product: an AI-assisted **Chinese web-novel writing workflow**, delivered as a web app. The core thesis (`PRODUCT_SPEC.md §1.5`) is to treat long-form novel writing like software engineering — establish architecture (worldbuilding/characters/outline), generate against spec, test every chapter, maintain a single source of truth.
