feat(perception): anomaly detection and recognition monologue during delay

Add AnomalyMarker component and detect_anomalies() system that flags
entities with KG relationship PersonOfInterest or Contradicted state
for urgent cognitive delay (0.3s vs 0.6s normal). Add
trigger_recognition_monologue() that fires monologue at delay START
(when grey blob appears), not at completion — the monologue IS the
recognition process per D-060. Includes v0.1 fallback recognition
lines and cooldown tracking. Fixes #450, #451.
