tmux.Pane.CaptureToBuffer(ctx: context.Context, buffer: string, request: CapturePaneRequest) -> error
```

CaptureToBuffer captures content from the receiver's exact linked pane into the nonempty named tmux buffer. The buffer is owned by tmux and no printed output is returned. A completed nonzero exit or stderr becomes a [CommandError].

Invalid requests fail before execution. Transport and context errors are
delivery-ambiguous: the buffer may already have changed.
