tmux.Server.SaveBuffer(ctx: context.Context, request: SaveBufferRequest) -> error
```

SaveBuffer writes a named or most-recent buffer to a file. Path follows [Server.SourceFile]'s current-user expansion and lexical normalization. It changes that file. Exact "-" is rejected because it names tmux's stdout rather than a path; [Server.SaveBufferTo] streams to an [io.Writer], and this method is the one that runs over a [Connection].
