Description
Add e2e tests to verify that reasoning_details (thought signature) are properly preserved in tool calls when using Gemini models with thinking enabled across multi-turn conversations.
The providerOptions containing reasoning_details must be preserved when passing response.messages from a first request to a second request, otherwise Gemini will reject the continuation. This was fixed in AI SDK v6.0.
Tests both
streamTextandgenerateTextAPIs to ensure the fix works for both.Closes #314
