```
io.github.libtmux.Server.Server.newSession(name: String) -> Session
```

Creates a detached session and returns that exact session.

<p>tmux reports which session it made, so the result is exact even when another session
already carries the same name.

<p>Keep {@code :} and {@code .} out of the name. tmux decides what to do with them and changes
its mind across the supported range: 3.2a through 3.6 rewrite each one to {@code _}, 3.7
refuses the name, and 3.7a onwards keeps it — where it then cannot address the session,
because a target splits on both. {@link Session#name()} reports what tmux settled on.
