failed to run that integrated with webpack-dev-server #209
Description
The webpack-dev-server example failed to run that integrated with latest @hono/node-server.
% npx webpack-cli serve
[webpack-cli] Error [ERR_SERVER_ALREADY_LISTEN]: Listen method has been called more than once without closing.

}I'm not sure which library should be responsible for listening to the server, but at least in certain versions there is no problem on the webpack-dev-server side, so I reported it here.

% npm ci
% npx webpack-cli serveMy guess
It seems to break after the below PR landed.
