-fix: use sub-message decoding for Error fields (not raw bytes)
-
-The kRPC proto defines error on Response and ProcedureResult as
-type Error (a sub-message), not raw bytes. The schema already
-declared it that way, so protobufjs was decoding the error as
-a nested Error object automatically.
-
-But our client code was treating response.error as if it were
-a Uint8Array of raw bytes (matching the wrong type annotation
-we had earlier), and we were trying to decode those bytes as
-a second Error message. That double-decode was the source of
-the "RPC error: .:" with stray substitute character and the
-"index out of range" errors when the bytes happened to look
-like other protobuf structures.
-
-Fix: use the auto-decoded error object directly. response.error
-is now { service, name, description, stackTrace } when set,
-and we just read those fields.
-
-This should also let the actual response values decode correctly,
-since we were previously mangling the error path.
