Agent Identity Publishing Readiness (Visa TAP / Mastercard Agent Pay)

Audit key freshness and rotation posture (art-132) → crosswalk identity posture to Visa TAP, Mastercard Agent Pay, and Web Bot Auth acceptance criteria (art-133) → emit a directory publish-readiness verdict with a precise gap list (art-134). Supply-side of the Ed25519 identity substrate.
