If a proto file already exists (committed to repo), don't overwrite it
with a placeholder. This allows first-time builds to work correctly
when the proto file is already in the repository.

Grpc.Tools needs service definitions to generate the base classes
(CommandService+CommandServiceBase, etc.) that GrpcGenerator looks for.
Without these, the service bases wouldn't exist on first build.

The WriteProtoFileTask now receives RootNamespace and AssemblyName from
MSBuild and uses them for the placeholder proto's csharp_namespace instead
of hardcoded "Generated.Grpc". This ensures GrpcGenerator can find the
service base types on first build, enabling gRPC service registration
to work without requiring a second build.
