Subject: [PATCH 09/17] [mscpp] Add grpc and protobuf as propagated
 dependencies

GrpcAdapter.h includes <grpcpp/grpcpp.h>, so consumers of mscpp
need grpc headers to be available. Adding grpc and protobuf as
propagatedBuildInputs ensures these headers are available to
downstream packages.

-      ***Under construction***
+      A performant C++ implementation of the orchestrator daemon, providing
+      job scheduling and execution capabilities via gRPC API.
+
+      Binaries:
+      - orchestratord-cpp: The daemon (renamed to avoid conflicts with Python orchestrator)
+      - orchestratorctl: CLI client for controlling the daemon
     '';
   };

Subject: [PATCH 15/17] Fix test script: remove redundant 'bash' prefix in job
 definition

The job definition was 'bash {input_0}' and the input was 'bash /path/to/script',
resulting in 'bash bash /path/to/script' which fails with exit code 126.

Changed job definition to just '{input_0}' since the input already includes 'bash'.
