feat(cursor): update model handling to use agentv1 responses and enhance CLI model details

- Refactored response handling in newProtoMessage to utilize agentv1 for GetUsableModelsResponse and GetDefaultModelForCliResponse.
- Added new tests for buildCLIModelDetails and encodeCLIModels to ensure correct model details and encoding.
- Updated buildUsableModelsPayload and buildDefaultModelForCliPayload to leverage buildCLIModelDetails for improved model data structure.
