```
server.serverAddress(runtime: : RuntimeContext) -> string | undefined
```

Which tmux this runtime addresses, or `undefined` when that is unknowable.

An engine's socket is a path on a machine this process cannot see, so the
socket alone does not name the daemon. Unknowable rather than guessed: an
engine that declares no endpoint is the one case where answering would mean
inventing the fact the comparison turns on.
