 * Create EVMChain from a viem PublicClient.

 * Supports ALL viem transport types including:
 * - http() - Standard HTTP transport
 * - webSocket() - WebSocket transport
 * - custom() - Injected providers (MetaMask, WalletConnect, etc.)
 * - fallback() - Fallback transport with multiple providers
 *
 * @param client - viem PublicClient instance with chain defined
 * @param ctx - Optional chain context (logger, etc.)
 * @returns EVMChain instance
 *
 * @example
 * ```typescript
 * import { createPublicClient, http } from 'viem'
 * import { mainnet } from 'viem/chains'
 * import { fromViemClient } from '@chainlink/ccip-sdk/viem'
 *
 * const publicClient = createPublicClient({

 *   transport: http('https://eth.llamarpc.com'),
 * })
 *
 * const chain = await fromViemClient(publicClient)
 * const messages = await chain.getMessagesInTx(tx)
 * ```
 *
 * @example Browser wallet (MetaMask)
 * ```typescript
 * import { createPublicClient, custom } from 'viem'
 * import { mainnet } from 'viem/chains'
 * import { fromViemClient } from '@chainlink/ccip-sdk/viem'
 *
