/**
* Approve an agent to sign on behalf of the master account.
*
* Signing: User-Signed EIP-712.
*
* @param config General configuration for Exchange API requests.
* @param params Parameters specific to the API request.
* @param opts Request execution options.
* @return Successful response without specific data.
*
* @throws {ValidationError} When the request parameters fail validation (before sending).
* @throws {TransportError} When the transport layer throws an error.
* @throws {ApiRequestError} When the API returns an unsuccessful response.
*
* @example Basic usage
* ```ts
* import { HttpTransport } from "@nktkas/hyperliquid";
* import { approveAgent } from "@nktkas/hyperliquid/api/exchange";
* import { privateKeyToAccount } from "npm:viem/accounts";
*
* const wallet = privateKeyToAccount("0x..."); // viem or ethers
* const transport = new HttpTransport(); // or `WebSocketTransport`
*
* await approveAgent({ transport, wallet }, {
* agentAddress: "0x...",
* agentName: "myAgent",
* });
* ```
*
* @example With expiration timestamp
* ```ts
* import { HttpTransport } from "@nktkas/hyperliquid";
* import { approveAgent } from "@nktkas/hyperliquid/api/exchange";
* import { privateKeyToAccount } from "npm:viem/accounts";
*
* const wallet = privateKeyToAccount("0x..."); // viem or ethers
* const transport = new HttpTransport(); // or `WebSocketTransport`
*
* const expirationTimestamp = Date.now() + 24 * 60 * 60 * 1000; // 24 hours from now
* await approveAgent({ transport, wallet }, {
* agentAddress: "0x...",
* agentName: `myAgent valid_until ${expirationTimestamp}`,
* });
* ```
