WFW-8 整章级再沟通（后端）。新增 POST /projects/{id}/chapters/{no}/rewrite（SSE）：
- rewrite.md 教条（品类无关内核，非 SPEC，仿 write_craft 经 load_prompt 读盘）；
- rewrite_node：build_rewrite_request 纯函数（system=[rewrite教条,stable_core] cache 前缀；
input=近况+当前草稿+作者意见，断点后不入缓存前缀——守不变量 #9）+ stream_chapter_rewrite；
- RewriteStreamRequest{feedback,prior_draft}（带 max_length 上界）；端点复用 assemble 记忆注入
+ normalize_deltas SSE，只读不写库（HITL，新版停前端接受才落，不变量 #3），是工具非写节点
（不破坏 章=f(outline,state) 纯函数，不变量 #7），项目不存在触网关前 404。
门禁绿：ruff / mypy 224 files / pytest（新增 test_rewrite_node 5 例 + 更新 doctrine 一一对应）/
alembic 无漂移。OpenAPI 含新路径 + schema（前端待 gen:api）。
