test(remotes): unwrap the Remote envelope in the built-lib chain

Every generated method resolves to RemoteResult, so the plain-Node script
must read the business value through `.value`: the CAS ref it passed on to
goals/edit was undefined, which the client codec rejected before the request
left. The invalid-payload case keeps its try/catch — a codec-rejected
argument still throws at the Client Remote face rather than folding into the
error branch.
