The crate, sdk-python and later the server read one copy of these messages. The gRPC service and its Nexus annotations come with the server.

What changed?
This PR adds the Stream service messages, marked experimental.
stream/v1/message.protohas the shared types,streamservice/v1/request_response.protohas the requests and responses, andenums/v1/stream.protohas the enums.StreamRef.owneris acommon.v1.Execution, the Workflow or Standalone Activity that owns the Stream.StreamRecorditems. Each holds oneoneof item: aStreamDataRecord, aSupersession, or theStreamClose.offsetstays outside theoneof.CreateStreamis create-or-get. A Stream that exists keeps its Retention, andcreatedis false.StreamErrorDetails.reasonis theStreamErrorReasonenum. Each case names its gRPC status code, so each SDK can map a reason to one error type.service.protoyet. It comes with the later stage of the project (Jetty).Why?
The SDKs and Redis already use these messages, so they need one home before a server serves them.
