feat(review): 人物塑造 advisory 审（第五审，仅建议不阻断验收）

写→审链新增第五审「人物塑造」（灵感③/D2）：advisory 单维——仅建议、不阻断
验收（不进 conflicts、不碰 assert_conflicts_resolved、不入 REVIEW_RESERVED_NAMES）；
只做人物塑造、不做氛围。

- SPEC characterization_spec（analyst，reads=("characters",)，writes=()）+
  prompts/characterization.md（只读、显式忽略文本长度与辞藻华丽度、引用逐字片段+置信度）
- schema CharacterizationReview{issues[...]}（全字段默认值守解析韧性）+ 注册 catalog
- 计数三处 22→23 + regen prompt_hashes.json（仅加一条）
- DB chapter_reviews 加 characterization JSONB nullable 列（迁移 f6a7b8c9d0e1）
- 接线：graph REVIEW_SPECS 追加 · chain ReviewRecordRepo · collect(extract/record) ·
  review_repo(Protocol/Sql/_to_view/ReviewView) · sse(event/factory/section) · normalize 自动纳入
- 契约 ReviewHistoryItem 加 characterization（gen:api 已重生成）
- 前端 sse/history/useReviewStream + CharacterizationPanel（只展示无裁决 UI、置信度降序+低置信折叠）+ ReviewReport 挂面板
- 测试 test_characterization_does_not_block_accept + 计数/golden + collect/normalize + 前端 reducer/normalize/parse

守不变量 #2/#3/#9；依赖 ⑧（motive/appearance 作客观锚点）。
