When the prober observes a NEW hash for an
(attacker_uuid, port, probe_type) triple it has seen before — VPS
rotation, SSH server rebuild, TLS cert swap — emit a derived
attacker.fingerprint_rotated event carrying both old and new hash.
Detection is a small library (decnet.correlation.fingerprint_rotation)
called inline from the prober at each of the three emit sites
(JARM/HASSH/TCPFP). No new daemon. New AttackerFingerprintState table
holds per-triple last-hash state; Attacker.rotation_count and
Attacker.last_rotation_at are stamped on every diff. Library is sync,
fully unit-tested via injected publish_fn / syslog_fn callbacks.
