x402 Spend-Evidence VPSF Bridge

Renders the x402-spend-evidence chain's assembled x402_spend_evidence pack (EIP-712 digest recompute, ECDSA signer recovery, domain/nonce/window check) as a VPSF SettlementReceipt + DelegationGrant Payment Claim pair, JCS-hashed via RFC 8785 canonicalisation and SHA-256, joined by a Conjunction composite. Verifiable offline by any VPSF-conformant verifier, including this suite's own VPSF Claim Algebra Verifier. Structural evidence only: never a settlement-finality claim.
