KYA Credential x x402 Payload Scope Verifier

Cross-checks a declared KYA (Know Your Agent) credential's scope against a declared x402 PaymentPayload: amount vs the credential's spend cap, network/asset vs its allowed set, payee vs its merchant allowlist, validity window vs the payload's timestamps, and scope-string coverage of the payment scheme. Returns findings[] and a verdict of IN_SCOPE, OUT_OF_SCOPE, or INDETERMINATE (when the credential omits a claim the payload requires -- never guessed). Verify-only: never fetches either input, never contacts Skyfire or a facilitator, performs no signature verification, and never initiates or settles an x402 payment.
