tmuxtest.RunInPane(ctx: context.Context, t: testing.TB, command: string) -> tmux.Pane
```

RunInPane creates an isolated pane, waits for its startup-file-free POSIX shell, and submits command with [Type]. It does not wait for command to start or finish. Resources belong to t; setup failures call [testing.TB.Fatal]. Use [NewServerWithOptions] for custom topology or configuration.
