LibTmux.Mcp.PaneActivityHub.WaitForActivityAsync(paneId: string, signalBefore: object?, timeout: TimeSpan, cancellationToken: CancellationToken) -> Task<bool>
```

Waits until a pane prints something, or the time runs out.

## Parameters

- `paneId` (string): The pane to wait on.
- `signalBefore` (object?): The signal captured before the caller last read the pane. Passing the
one taken before the read is what stops output that arrived during it
from being missed.
- `timeout` (TimeSpan): How long to wait at most.
- `cancellationToken` (CancellationToken): Stops waiting.

## Returns

<see langword="true" /> when the pane printed something.
