io.github.libtmux.SessionSpec.SessionSpec.detached() -> boolean

Always true, and not a choice.

<p>{@code new-session} attaches unless told not to, and attaching needs a terminal — from a
process without one it fails with {@code open terminal failed}. A library is usually called
from something that has no tty, so the session is always created detached. {@link WindowSpec}
and {@link SplitSpec} default the other way, because their commands need no terminal.
