Consider adding option to force close - killing all in-flight connections.

The after hook can hang if a test fails without closing all responses:

                def after
                    @client&.close
                    @server_task&.stop
                    @bound_endpoint&.close

                    super
                end

Maybe introduce @client&.close(force = true) OR @client&.stop (force close). I'm a little worried about side effects since the connection pool may not contain all active connections.

You could reproduce this behaviour with a test response = client.get then raises an exception in sus.
