/**
 * Creates an object with methods for generating a dummy signature, signing user operation hashes, signing messages, and signing typed data.
 *
 * @example
 * ```ts
 * import { nativeSMASigner } from "@account-kit/smart-contracts";
 * import { LocalAccountSigner } from "@aa-sdk/core";
 *
 * const MNEMONIC = "...":
 *
 * const account = createModularAccountV2({ config });
 *
 * const signer = LocalAccountSigner.mnemonicToAccountSigner(MNEMONIC);
 *
 * const messageSigner = nativeSMASigner(signer, chain, account.address);
 * ```
 *
 * @param {SmartAccountSigner} signer Signer to use for signing operations
 * @param {Chain} chain Chain object for the signer
 * @param {Address} accountAddress address of the smart account using this signer
 * @param {Hex} deferredActionData optional deferred action data to prepend to the uo signatures
 * @returns {object} an object with methods for signing operations and managing signatures
