Why need this and when is it used? Don't see where any instances are constructed in the PR.

It is a wrapper class for a public integration API. It is required for external notebook environments, such as colab notebook and BigQuery Studio. This wrapper class allow external integrations to wrap their query executions and display a deferred widget, such as showing dry-run info and "Run Query" Button, instead of executing the query immediately when a cell runs. When the user clicks the "Run Query" button in the UI, the widget triggers .execute() on this wrapper to compute the query and display the actual DataFrame. Since it is intended to be instantiated by external platforms calling into BF, we don't construct any instances of it within the BF library itself.

This PR introduces support for deferred execution rendering in TableWidget (the anywidget-based interactive table viewer for Jupyter notebooks). Users can now view dry-run estimations (e.g., query size/cost) and trigger execution directly from the notebook output.
