When using session.respond() (non-streaming), the transcript only contains .prompt() entries but no .response() entries for the model's text output.

Expected Behavior

The transcript should contain both .prompt() and .response() entries after each interaction, similar to how streaming works.

Actual Behavior

The transcript only contains .prompt() entries. The model's response text exists in response.content but is never added to the transcript as a .response() entry.
