// scripts/sync-work-order-to-notion.js
// 📋 铸渊工单 → Notion SYSLOG 同步器
//
// 架构说明:
//   工单是铸渊智能运维的核心记录单元
//   冰朔需要在 Notion 侧看到告警工单的完整上下文
//   复用已有的 SYSLOG 数据库（霜砚已在 Notion 侧建好）
//   不需要新建数据库，零额外配置成本
//
// 用法:
//   node scripts/sync-work-order-to-notion.js --order-id <WO-xxx>
//   node scripts/sync-work-order-to-notion.js --order-id "observer-23906843495"
//   node scripts/sync-work-order-to-notion.js --all-failed   (同步所有失败工单)
//
// 环境变量:
//   NOTION_TOKEN   GitHub Secret: NOTION_TOKEN (必须)
//   SYSLOG_DB_ID   覆盖默认数据库 ID (可选)
//   COMMIT_SHA     当前 commit SHA (可选，由 workflow 注入)
//   RUN_ID         工作流运行 ID (可选，由 workflow 注入)
//   WORKFLOW_NAME  工作流名称 (可选，由 workflow 注入)
//
// Notion「📥 GitHub SYSLOG 收件箱」数据库属性:
//   标题       title       工单ID + 任务名
//   DEV编号    select      "SYSTEM" (系统工单)
//   文件内容   rich_text   工单完整 JSON + 时间线
//   接收时间   date        工单创建时间
//   处理状态   status      待处理 / 人工干预
//   来源路径   rich_text   data/work-orders/active.json
//   commit_sha rich_text   工单关联的 commit SHA
//   推送方     rich_text   铸渊
