tmux.Pane.CaptureBytes(ctx: context.Context, request: CapturePaneRequest) -> ([]byte, error)
```

CaptureBytes captures printed content from the receiver's exact linked pane as caller-owned stdout bytes. It preserves tmux's output delimiters and trailing newlines after tmux has interpreted the pane's terminal contents.

Its validation and failure behavior match [Pane.Capture], including returning
partial bytes with transport or context errors.
