"""PromptProvider(Task 6): 租户提示词四件套 + $DEFLECTION_POOL 单一事实源注入。

- 提示词从租户目录(seed_profiles/<slug>/prompts)读,不再有代码级
  app/engine/prompts 副本;
- system.md 的迂回话术枚举段替换为 $DEFLECTION_POOL 占位符,组装时注入
  wall.json deflections 池(话术只存 wall.json 一份,改一处两边同步变);
- extractor/evaluator 的 $existing_info/$messages/$profile/$recent_messages
  替换逻辑从 AIService 原样搬入 Provider(行为等价)。

路径纪律: 一律 Path(__file__) 锚定仓库根,禁 cwd 相对。
