Subject: [PATCH] fix(gemini): rename field to thoughtSignature for native REST
 API compliance

- The native Gemini REST API requires camelCase 'thoughtSignature' as a sibling to functionCall.
- Explicitly rename the field to match this requirement, resolving the 'missing thought_signature' 400 error.
