Module signing 

Hyperliquid EIP-712 signing delegated to motosan-wallet-core.

Public API signatures are preserved for backward compatibility. Internally, a SingleAddressSigner bridges the hyper-exchange Signer trait to motosan-wallet-core’s [HlSigner] so the actual EIP-712 logic lives in one place.
