Bug

nerve start 启动正常，但关闭时（Ctrl+C 或超时）抛 unhandled EPIPE：

Error: write EPIPE
    at target._send (node:internal/child_process:876:20)
    at sendShutdown2 (.../nerve-daemon/dist/index.js:1004:12)
    at Object.stop (.../nerve-daemon/dist/index.js:1373:7)

Cause

Worker child process 已经退出，daemon 的 stop() 仍然尝试通过 IPC process.send() 发 shutdown 消息。

Fix

在 sendShutdown2 / stop() 里检查 child process 是否还活着（child.connected / child.killed），如果已退出则跳过 send。同时给 child process 加 error 事件监听防止 unhandled。
