ERC-8350 Agent Memory State Registry Draft Submitted

ERC-8350: Agent Memory State Registry draft submitted in ethereum/ERCs#1910, awaiting editor review. Public Sepolia deployment is live. It sequences agent-memory state transitions onchain while keeping latent vectors private. Each transition requires sequence == currentSequence + 1 and prevStateRoot == currentStateRoot, preventing rollbacks, forks, or gaps. EAS lacks successor uniqueness, making this standard necessary.
