This commit: - Adds documentation explaining the SDK limitation - Updates tests to reflect that OpenAI filters out "minimal" while OpenRouter preserves it - Ensures consistency in how different providers handle reasoning parameters The original PR correctly implements passing "minimal" through for OpenRouter.
