/**
* Cross-Model Thinking Signature Test
*
* Tests that switching between Claude and Gemini models mid-conversation
* properly handles incompatible thinking signatures.
*
* Scenarios tested:
* 1. Claude → Gemini: Claude thinking signatures should be dropped
* 2. Gemini → Claude: Gemini thinking signatures should be dropped
* 3. Both should still work without errors (thinking recovery kicks in)
