Overview

gRPC server runner implemented using GRPC::RpcServer.

This is a convenience server implementation for running a gRPC service in-process under Nonnative’s server lifecycle. It binds to the configured proxy ‘host`/`port` and is started/stopped by Server via #perform_start / #perform_stop.

Important note about logging: the ‘grpc` gem uses a global logger. This implementation sets `GRPC.logger` to write to the configured `service.log`, and whichever gRPC server is initialized first “wins” that global logger.
