Exit with status 1 when the web server cannot listen (closes #73)

Server.Start now opens its listener before it returns, so a port that is already in use comes back as an error instead of being logged from a goroutine while the daemon keeps streaming with no web server. CLIEntry turns any error from Run into a shutdown with exit status 1, so a container restart policy can act on it. Model: opus-5-5

 # Completed Steps

+- 2026-10-14: the daemon exits with status 1 when it cannot listen on its
+  port, for example because the port is in use, instead of running on without
+  its web server; any other error from `Run` also stops it with status 1
+  (closes #73)
 - 2026-10-03: `/api/v1/stats` serves the prefix distribution from memory,
  seeded at startup and adjusted on every live-route write, so a request no
  longer reads every live route (closes #30)
