x402 Header Decoder, Payload Linter & 402 Flow Simulator

Decodes x402 PAYMENT-REQUIRED / PAYMENT-SIGNATURE / PAYMENT-RESPONSE headers, lints an exact-scheme PaymentPayload, walks the HTTP-402 request/verify/settle flow, and shows the scheme x network support matrix. exact-scheme authorization sub-fields are illustrative (EIP-3009 style) — verify against the x402 spec.
