// Package geminiCLI provides request translation functionality for Gemini to OpenAI API.
// It handles parsing and transforming Gemini API requests into OpenAI Chat Completions API format,
// extracting model information, generation config, message contents, and tool declarations.
// The package performs JSON data transformation to ensure compatibility
// between Gemini API format and OpenAI API's expected format.
