/**
 * Convert viem WalletClient to ethers-compatible Signer.
 *
 * Supports both:
 * - Local accounts (privateKeyToAccount, mnemonicToAccount)
 * - JSON-RPC accounts (browser wallets like MetaMask)
 *
 * Works with ALL viem transport types including:
 * - http() - Standard HTTP transport
 * - webSocket() - WebSocket transport
 * - custom() - Injected providers (MetaMask, WalletConnect, etc.)
 *
 * @param client - viem WalletClient instance with account and chain defined
 * @returns ethers AbstractSigner for use with sendMessage, manuallyExecute, etc.
 *
 * @example
 * ```typescript
 * import { createWalletClient, http } from 'viem'
 * import { privateKeyToAccount } from 'viem/accounts'
 * import { mainnet } from 'viem/chains'
 * import { fromViemClient, viemWallet } from '@chainlink/ccip-sdk/viem'
 *
 * const account = privateKeyToAccount('0x...')
 * const walletClient = createWalletClient({
 *   chain: mainnet,
 *   transport: http('https://eth.llamarpc.com'),
 *   account,
 * })
 *
 * const chain = await fromViemClient(publicClient)
 * const request = await chain.sendMessage(
 *   router,
 *   destChainSelector,
 *   message,
 *   { wallet: viemWallet(walletClient) }
 * )
 * ```
 *
 * @example Browser wallet (MetaMask)
 * ```typescript
 * import { createWalletClient, custom } from 'viem'
 * import { mainnet } from 'viem/chains'
 * import { viemWallet } from '@chainlink/ccip-sdk/viem'
 *
 * const walletClient = createWalletClient({
 *   chain: mainnet,
 *   transport: custom(window.ethereum),
 *   account: connectedAccount,
 * })
 *
 * // Works with injected providers!
 * const signer = viemWallet(walletClient)
 * ```
