tmux.Server.AttachSession(ctx: context.Context, request: AttachSessionRequest) -> error
```

AttachSession attaches the caller's terminal to a matching session and blocks until detach or context cancellation. Nil standard streams inherit the process streams; each stream must be a concrete terminal descriptor. The call retains caller-supplied files while attached and never owns or closes them. A completed nonzero exit returns [CommandError]; cancellation can end waiting but does not prove that attachment or detachment did not occur.
