gRPC Rich Error Model

Server implementation of the gRPC Rich Error Model for Node.js, providing structured error details like retry info, error info, debug info, and more. Version 0.0.21 is the latest stable release, updated with TypeScript support and matching the gRPC specification. The package fills a gap in the official Node.js gRPC library, which lacks rich error support, unlike gRPC-Web. It integrates seamlessly with @grpc/grpc-js and offers a builder pattern for creating complex error responses.
