// Package gemini provides request translation functionality for Claude API.
// It handles parsing and transforming Claude API requests into the internal client format,
// extracting model information, system instructions, message contents, and tool declarations.
// The package also performs JSON data cleaning and transformation to ensure compatibility
// between Claude API format and the internal client's expected format.
