/**
 * Signs an EIP-7702 authorization for ZeroDev kernel delegation.
 *
 * This function creates a signed authorization that allows a wallet to delegate
 * its execution to the ZeroDev kernel contract. The signed authorization can then
 * be passed to `createEcdsaKernelAccountClientWith7702` via the `eip7702Auth` parameter.
 *
 * @param params - The parameters for signing the authorization.
 * @param params.signer - The wallet client (signer) to sign the authorization with.
 * @param params.chainId - The chain ID to use for signing.
 * @returns A promise that resolves to the signed EIP-7702 authorization.
