Bridge that lets a local engine subscribe to a remote ReifyDB instance and forward incoming change payloads into a local channel or sink. Wraps the gRPC client, handles authentication, and proxies raw RBCF payloads through a conversion callback so the caller controls how remote events are typed.
This is the only place in the workspace where external wire-format payloads are turned into events the local
engine consumes; doing the conversion anywhere else would couple unrelated subsystems to the gRPC client and
wire-format decoders.
