/**
|

* insightService.ts
|
||||
*
|
||||
* AI 见解后台服务：
|
||||
* 1. 监听 DB 变更事件（debounce 500ms 防抖，避免开机/重连时爆发大量事件阻塞主线程）
|
||||
* 2. 沉默联系人扫描（独立 setInterval，每 4 小时一次）
|
||||
* 3. 触发后拉取真实聊天上下文（若用户授权），组装 prompt 调用单一 AI 模型
|
||||
* 4. 输出 ≤80 字见解，通过现有 showNotification 弹出右下角通知
|
||||
*
|
||||
* 设计原则：
|
||||
* - 不引入任何额外 npm 依赖，使用 Node 原生 https 模块调用 OpenAI 兼容 API
|
||||
* - 所有失败静默处理，不影响主流程
|
||||
* - 当日触发记录（sessionId + 时间列表）随 prompt 一起发送，让模型自行判断是否克制
