Fix fast connection closing

[roxblnfk]

What was changed

Added a constant delay of 100ms before an instant disconnect.
Run command now consumes signals
Added Cancellable and Destroyable interfaces

Why?

In some cases, the connection to the client closes too quickly. The client doesn't have time to receive all the content.

This problem could have been solved by removing this fragment:

trap/src/Socket/Server.php

Lines 40 to 41 in 929ce1f

	/** @link https://github.com/buggregator/trap/pull/14 */
	\socket_set_option($this->socket, \SOL_SOCKET, \SO_LINGER, ['l_linger' => 0, 'l_onoff' => 1]);

but the convenience of restarting the server is still important.
