fix(qa): 实施 4 组设计型 QA 项——规则删除/codex 角色/大纲卷过滤/文风回炉锚点

#5 规则 DELETE + id：暴露 RuleView.id（PK）；新增 DELETE /projects/{id}/rules/{rule_id}
  （项目/规则不存在→404，成功→204，按 (id,project_id) 限定）；rule_repo 加
  list_for_project/delete；RulesPage 每条加删除（乐观删+回滚+toast）。assemble 侧
  RuleView（缓存前缀）不动，列表另立 RuleListItemView。
#7 codex 角色 relations：写侧本已持久化、读端点 _existing_characters 硬编码 []。
  加 _relations_from_jsonb 解析 {name,kind,note}，CodexPage 渲染关系 chip。
#8 角色入库幂等：SqlCharacterWriteRepo.create 改 (project_id,name) app 层 upsert——
  重复入库改更新而非插入；不加 UNIQUE/迁移（线上已有重复行会让约束迁移失败）。
#1 大纲卷过滤：GET /outline 支持可选 ?volume（无参=全部，向后兼容）；OutlineEditor
  加「查看：全部/卷N」筛选，与生成目标卷解耦。
H3/#9 文风回炉锚点：StyleDriftSegment 加 text（逐字命中段），style.md 指示审稿输出；
  前端按内容锚点定位回炉目标（idx 仅排序），命中失败 → 提示「无法定位该段」而非
  静默 no-op。style golden fixture 已重生成。

契约变更已 pnpm gen:api（RuleView.id / DELETE rules / outline ?volume）。无迁移
（alembic 无漂移）。门禁绿：ruff/mypy(210)/alembic/pytest 760 · 前端 tsc/lint/vitest 329。
