feat(sdk): Sync with latest OpenAPI specification

- Add OllamaCloud and Mistral providers to Provider enum
- Update Display and TryFrom implementations for new providers
- Add Serialize derive to ChatCompletionMessageToolCallChunk
- Add logprobs field to ChatCompletionChoice
- Add reasoning_format field to request/response types
- Update all tests to include new providers and logprobs field
