feat(llm): 整章重写预检澄清 spec + 教条 clarify_rewrite（WFW-9 M2）

镜像 clarify_refine（仅 name/prompt 不同，复用 ClarifyDecision，不新增 schema）：
新增 clarify_rewrite_spec（analyst 档、reads=()/writes=() 只读，不变量 #2/#3）+ 章级
教条 prompts/clarify_rewrite.md（segment→整章：判作者章级重写意见是否含糊）。注册进
SPECS/SCHEMA_CATALOG，自检数量 24→25，__init__ 导出，金标准仅新增 1 条哈希无漂移。
