// 集成测试用的「假 worker」：走完整 outbox 协议，但【不调用 SDK / 不建 worktree】，零 token。
// 用法：daemon 通过 MAESTRO_WORKER_CMD='npx tsx test/fixtures/fake-worker.ts' spawn 它，argv[2]=runId。
// 行为：emit started + 持续刷心跳；轮询 runs/<runId>/finish 哨兵文件出现后 emit result+done 退出。
// 收到 SIGTERM → emit failed+done 退出。模拟一个「在跑的真进程」，供测试验证 spawn / 心跳 / re-adopt / ingest。
