 * @title DeploySmartAccountsKit
 * @notice Deploys Smart Accounts Kit contracts (EntryPoint, AccountFactory, Paymaster)
 * @dev This script deploys the core ERC-4337 contracts needed for MetaMask Smart Accounts Kit
 * 
 * NOTE: MetaMask Smart Accounts Kit uses standard ERC-4337 contracts:
 * - EntryPoint: Standard ERC-4337 EntryPoint contract
 * - AccountFactory: Factory contract for creating smart accounts
 * - Paymaster: Optional contract for gas abstraction
 * 
 * These contracts may need to be:
 * 1. Deployed from MetaMask's provided contracts (if available)
 * 2. Deployed from standard ERC-4337 implementations (e.g., OpenZeppelin, Alchemy)
 * 3. Or use existing deployed addresses if available on ChainID 138
