/**
 * OKX 模块统一配置。
 *
 * <p>通过 Builder 模式集中管理所有运行参数，避免参数散落在多个文件中。
 * 提供 REST API 和 WebSocket 地址的自动环境切换（模拟盘/实盘）。
 *
 * <h3>使用示例</h3>
 * <pre>
 *   OkxConfig config = OkxConfig.builder()
 *       .apiKey("...")
 *       .secretKey("...")
 *       .passphrase("...")
 *       .contract("BTC-USDT-SWAP")
 *       .leverage("100")
 *       .gridRate(new BigDecimal("0.0035"))
 *       .contractMultiplier(new BigDecimal("1"))
 *       .isProduction(false)
 *       .build();
 *
 *   String wsKlineUrl = config.getWsKlineUrl();
 *   String wsPrivateUrl = config.getWsPrivateUrl();
 * </pre>
 *
 * <h3>默认值</h3>
 * <ul>
 *   <li>合约: BTC-USDT-SWAP, 杠杆: 100x, 全仓</li>
 *   <li>网格间距: 0.35%, 队列容量: 50, 保证金比例上限: 20%</li>
 *   <li>止盈: 5 USDT, 亏损上限: 15 USDT</li>
 *   <li>数量: 1 张, 合约乘数: 1, 环境: 模拟盘</li>
 * </ul>
