```
tmux.Server.SessionByName(ctx: context.Context, name: string) -> (Session, error)
```

SessionByName performs a live lookup of the session tmux knows by name and returns a newly materialized record. A name no session holds reports [ErrNotFound].

tmux keeps session names unique, so a name identifies one session for as
long as it keeps it. A [SessionID] does not change, which is why the records
this package hands back carry one and [Server.Session] takes one; a name is
what a person types and what a workspace file records.
