/**
 * LitActionPkpEthersWallet - An ethers-compatible wallet implementation for use within Lit Actions
 *
 * This class provides an ethers.js Signer-compatible interface that uses Lit's PKP signing
 * capabilities within a Lit Action execution environment. Unlike PKPEthersWallet which is
 * designed to run outside Lit Actions and uses the Lit SDK to make signing requests,
 * this wallet runs INSIDE a Lit Action and directly calls Lit.Actions.signAndCombineEcdsa.
 *
 * Key differences from PKPEthersWallet:
 * - No provider/RPC logic (runs in Lit Action sandbox)
 * - Direct use of Lit.Actions.signAndCombineEcdsa instead of SDK methods
 * - Simplified constructor (just takes PKP public key)
 * - No transaction population (gas estimation, nonce, etc.)
 *
 * Supports:
 * - signMessage: Sign arbitrary messages (EIP-191)
 * - _signTypedData: Sign EIP-712 typed data
 * - signTransaction: Sign raw Ethereum transactions
 *
 * @example
 * ```typescript
 * const wallet = new LitActionPkpEthersWallet({
 *   pkpPublicKey: '0x04...',
 *   sigName: 'my-signature'
 * });
 *
 * // Sign a message
 * const signature = await wallet.signMessage('Hello World');
 *
 * // Sign typed data (EIP-712)
 * const typedSignature = await wallet._signTypedData(domain, types, value);
 *
 * // Sign a transaction
 * const signedTx = await wallet.signTransaction(transaction);
 * ```
