def attach: (
  session: ::LibTmux::EntityRef,
  terminal: ::IO,
  term: ::String,
  ?read_only: bool,
  ?timeout: ::Numeric?,
  ?cancel: untyped
) -> ::LibTmux::TerminalResult
```

Blocks until the owned interactive client exits. The caller supplies and
retains its TTY. Cancellation detaches this client, not pane commands.

Behavior contract: Terminal attachment.

- `terminal` (`::IO`)
