Pull Request Overview

This PR adds error reporting functionality for metadata fetching failures by exposing structured error information when off-chain metadata cannot be fetched or validated. The change enables API consumers to understand why metadata retrieval failed and handle errors appropriately.

Key changes:

• Added optional error object to metadata schemas with standardized error codes and human-readable messages
• Updated TypeScript type definitions to reflect the new error field
• Added comprehensive test coverage for the new error structure
