Register an ERC-20 (including B20) for DIRECT credentials
Registers an ERC-20 contract on Base or Base Sepolia for DIRECT credentials (x402/ap2/mpp). Use source byo for your own ERC-20, or source b20 for a B20 token (ERC-20 compatible), including Credential Tokens. Validates the contract on-chain and reads decimals/symbol/name. Idempotent per (owner, network, contract).
