x402 Payment Envelope Verifier

Offline verifier for x402 PaymentPayload envelopes (the exact-scheme EIP-3009-style payload shape). Checks header well-formedness (x402Version, scheme, network), the authorization sub-object's required fields, and the signature's structural shape, and -- when a PaymentRequirements body is also pasted -- checks amount/asset/recipient consistency between the two documents. Never recovers a signer address or claims a signature cryptographically verifies; that recovery is art-591-x402-signer-recovery-verifier's job, cited not duplicated. Never originates, funds, or settles a payment. Zero network calls.
