tmux.Pane.OpenObservation(ctx: context.Context) -> (*PaneObservation, error)
```

OpenObservation captures the pane's visible text and returns an owned observation whose notifications begin at the capture's exact control-wire boundary. It resolves the pane's exact linked session before opening a dedicated control client. The caller must close the result.
