Every generated Remote method now resolves to `RemoteResult<T>`: the Client
face folds a carrier failure, a transport throw and a rejected result payload
into one error branch, so no consumer wraps a call to recover them. Only
assembly faults still reject — a wrong argument count, an unmounted method, a
missing Context binder, an absent Connection.
`RemoteFailure.code` stays an open string because the closed RPC code union
lives in the carrier package, which already depends on type-meta; naming it
here would invert that edge.
The goal surface drops its own try/catch plus the structural probe that
guessed whether a thrown cause was an RPC failure, and reads the result
instead.
