// between Claude Code API format and the internal client's expected format.

// ConvertClaudeRequestToCodex parses and transforms a Claude Code API request into the internal client format.
// It extracts the model name, system instruction, message contents, and tool declarations
// from the raw JSON request and returns them in the format expected by the internal client.
// The function performs the following transformations:
// 1. Sets up a template with the model name and Codex instructions
// 2. Processes system messages and converts them to input content
// 3. Transforms message contents (text, tool_use, tool_result) to appropriate formats
// 4. Converts tools declarations to the expected format
// 5. Adds additional configuration parameters for the Codex API
// 6. Prepends a special instruction message to override system instructions
//
// Parameters:
// - modelName: The name of the model to use for the request
// - rawJSON: The raw JSON request data from the Claude Code API
// - stream: A boolean indicating if the request is for a streaming response (unused in current implementation)
//
// Returns:
// - []byte: The transformed request data in internal client format
