/**
 * Internal Adapter: Maps Arvo's generic Agent Message format to Anthropic's specific API format.
 *
 * Handles:
 * - Mapping Tool Results to their originating Tool Call IDs.
 * - Multimodal Content (converting Arvo media objects to Anthropic Image source format).
 * - Reconstructs the specific message ordering Anthropic expects (User -> Assistant(ToolUse) -> User(ToolResult)).
 *
 * Note: Anthropic does not use a system message in the messages array - it's passed separately.
