// Package geminiCLI provides response translation functionality for OpenAI to Gemini API.
// This package handles the conversion of OpenAI Chat Completions API responses into Gemini API-compatible
// JSON format, transforming streaming events and non-streaming responses into the format
// expected by Gemini API clients. It supports both streaming and non-streaming modes,
// handling text content, tool calls, and usage metadata appropriately.

// Parameters:
//   - ctx: The context for the request.
//   - modelName: The name of the model.
//   - rawJSON: The raw JSON response from the OpenAI API.
//   - param: A pointer to a parameter object for the conversion.
//
// Returns:
//   - []string: A slice of strings, each containing a Gemini-compatible JSON response.
