/**
 * demo-harness-company.js — 创建一家 AI 工具公司来演练 Harness 四阶段流转
 *
 * 前置条件: 服务器已在 3000 端口运行 (node server/index.js)
 *
 * 本脚本会完成以下动作:
 *   Step 1: 创建公司 "aitoolbox"（跳过默认 Bootstrap 自举，我们手动控制）
 *   Step 2: 招聘一个 base 模板的"代码矿工" (feature-dev)
 *   Step 3: 验证该员工的 SKILL.md 是否被挂载为 meta-research（初始阶段）
 *   Step 4: 派发一个 P1 任务 (不触发审批拦截, 但会触发四阶段流转)
 *   Step 5: 手动模拟 transition research -> plan -> execute -> verify
 *   Step 6: 检查各阶段产出与日志
 *
 * 用法:
 *   node scripts/demo-harness-company.js

💡 接下来你可以:
   1. 用 UI 打开 ${WORKER_ID} 跟它对话，观察它的受限行为
   2. 派发一个 P0 任务测试审批拦截:
      node bin/lemon.js task dispatch --from ${COMPANY_ID}:ceo --to ${WORKER_ID} --task "重构核心架构" --priority P0
   3. 查看 billing.log: cat data/logs/billing.log
