/**
 * LitActionsSmartSigner for EIP-7702 delegated transactions
 *
 * This signer implements the Alchemy SmartAccountSigner interface to support
 * EIP-7702 delegation with the Lit Protocol PKP. It enables gasless transactions
 * through integration with Alchemy's gas sponsorship.
 *
 * @example
 * ```typescript
 * const signer = new LitActionsSmartSigner({
 *   pkpPublicKey,
 *   chainId,
 * });
 *
 * // Use with Alchemy's Smart Account Client, and pass as the signer.
 * ```
