Upgrading past opaque-ke 4.0.0 (opaque 1.0.0+) breaks deserialization of serverSetup values created under 3.x, since the dummy-user record's encoding changed from a private key to the corresponding public key. This adds a migration function (and matching CLI command) that re-encodes an old setup in place, preserving the real OPRF seed and AKE key so existing registrationRecords keep working unmodified. Trims incidental whitespace from the input since it's typically pasted in from a shell or config file.

migrateSetupFromV3converts aserverSetupfrom any pre-1.0 release (0.8.2 through 0.9.x, all onopaque-ke3.x — confirmed via pinned dependencies) into the format 1.x+ requires (opaque-ke4.x). It's a re-encoding, not a rotation: the OPRF seed and real AKE private key pass through unchanged, so existingregistrationRecord's keep working with no changes of their own.
