Add comprehensive tests for Anthropics and Gemini transformers
- Implement tests for anthropicMessagesTransformer including serialization and event handling in stream.test.ts. - Add usage extraction tests for anthropicMessagesUsage in usage.test.ts. - Create extensive tests for Gemini generate content aggregation and outbound usage in aggregator-outbound-usage.test.ts. - Introduce tests for Gemini stream handling and payload parsing in stream.test.ts. - Enhance OpenAI response serialization tests to ensure proper mapping of usage details and preservation of annotations in outbound.test.ts.
