Rootle gRPC Client Interceptor

A TypeScript-based gRPC client interceptor that integrates with Rootle log API for logging gRPC errors, currently at stable version 0.0.4. It allows specifying request fields to use as referer and user-agent via an InterceptorRequestSources interface. The interceptor is used as a custom gRPC interceptor passed to a gRPC client, enabling structured error logging. Compared to manual logging, it provides a drop-in solution for Rootle logging without modifying client code.
