Offline EIP-191 verify of a signed nsgoods response. Identifies the service from the
manifest (or the optional service arg), strips exactly that service's post-sign fields,
canonicalises (JCS, both ASCII modes), recovers the signer and checks it against the
published manifest signers. Reproduction-attestation (JCS/byte-length) and envelope
(signer/signature, components) shapes are reported as unsupported_shape, not verified here.
