Pull #267

github

Add Ethers.Siwe.verify/3 end-to-end SIWE verification

The one-call backend flow: parse the raw EIP-4361 message (or accept an
already-parsed struct), run stateless field validation, then check the
signature via Ethers.Signature.verify_message/4 — EOA signatures verify
locally with zero RPC round-trips while ERC-1271 and ERC-6492
smart-contract wallets are verified with a single eth_call. When given a
string, the signature is verified over the exact original input.
