Built-in Gemini agent runs now use Google's native protocol instead of its OpenAI-compatible endpoint. This changes the route used for model calls that could stall on follow-up turns.

Bedrock and SageMaker credentials now travel with each call instead of being set in the shared process environment. The Python SDK also accepts an AGENTA_API_URL without a URL scheme, and CSV preview comments no longer show a stray colon when a column has no header.
