check / check (push) Waiting to run
`Server.Start` opened its port inside a goroutine and returned nil at once, so a port already in use was only logged and the daemon kept running with no web server. It now opens the listener before returning and returns that error; serving runs in the background on the open listener. `CLIEntry` turns an error from `Run` into an fx shutdown with exit status 1, after the normal stop sequence, so a container restart policy can act. A serving error after a successful listen is still only logged. Model: opus-5-5
