A tmux session id, such as {@code $0}.

<p>Stable for the life of the session, unlike a session name, which a user can change at any
time. A separate type from {@link WindowId} and {@link PaneId} because tmux accepts any of them
as {@code -t} syntax: passing the wrong one is not an error tmux reports, it simply addresses
nothing.
