• The fallback value for topP is set to assistant.Temperature; confirm if this is intentional or if it should use assistant.TopP instead.

topP: assistant.ReasoningEffort > 0 ? assistant.TopP : assistant.Temperature,

Pull Request Overview

This PR fixes an issue with the serialization of the Assistant Reasoning Model by updating CreateRunAsync to conditionally pass temperature and topP parameters based on ReasoningEffort and adding a new streaming test.

• Updated CreateRunAsync to set temperature and topP to null when ReasoningEffort is active, and pass the reasoningEffort parameter.
• Added a new test (Test_06_02_CreateRun_Reasoning_Streaming) to cover streaming functionality for reasoning.
• Removed an unused using directive in the test file.

• Ensure that the CreateRunRequest constructor accepts null values for 'temperature' and 'topP' when ReasoningEffort is greater than zero to avoid type or serialization issues.

temperature: assistant.ReasoningEffort > 0 ? null : assistant.Temperature,
