Verified ERC-4337 and A402; added ZeroClick deployment

Verified two former drafts against primary sources: ERC-4337 (account-abstraction custody primitive, now live) and A402 (a research-stage architecture, now proposed). ZeroClick was reclassified from a draft protocol to a real deployment, since it is a storefront/proxy built on x402 and MPP rather than a new rail.
