Active x402 registration-v1

Reputation layer for autonomous on-chain agents. Blends four signal tiers — x402 receipts, behavioral evidence, declared identity, social attestation — into a portable Provider + Consumer karma score, plus an orthogonal Autonomy Confidence axis. Non-routing: AK scores wallets, it does not proxy paid calls.
