/**
 * AiModule — harness 入口。
 *
 * 分层:
 *   core/             基建(provider 工厂、缓存、安全门、调用记录)
 *   calls/            一个目录一个 AiCall(prompt + schema + safety rules + fallback)
 *   orchestrators/    业务编排(从 DB 装 input → runner.run → 落业务表)
 *   ai-call-runner    harness 统一执行器(任何 AiCall 都走这里)
 *
 * 加新 AiCall 步骤:
 *   1. calls/<call-key>/ 下放 prompt.ts + schema.ts + input.types.ts + call.ts
 *   2. 在本 module providers + exports 注册
 *   3. 在 orchestrators/ 下加一个业务编排(读 DB、装 input、调 runner、写业务表)
 *
 * 加新 orchestrator(如 plan-summary)同样套这个模板。
