/**
 * OpenAI-specific message builders for OTel gen_ai attributes.

 *   messages need special handling
 * - Response messages are flat (content is string, tool_calls/refusal/audio are separate fields)
 *
 * These builders convert OpenAI SDK shapes into OTel-shaped objects,
 * which are then serialized by the shared serializers in instrumentation-utils.
