io.github.libtmux.Server.Server.killServer() -> void
```

Ends the tmux server and every session on it.

Deliberately explicit and deliberately not what {@link #close()} does: closing a client is
not a reason to end everyone else's sessions.

Killing a server that has already gone is not a failure. Which is harder to detect than it
sounds: tmux answers a doomed request with {@code no server running} most of the time, but
with {@code server exited unexpectedly} when it reaches a socket whose server is still
exiting — on every release from 3.3a onwards, and on one in five attempts on 3.7. So the
postcondition is checked rather than the wording, which has changed before and says nothing
a second look cannot answer better.
