+/**
+ * Workaround for Node.js 20+ "Happy Eyeballs" (RFC 6555) causing AggregateError
+ * in libraries using @cypress/request (e.g., node-telegram-bot-api).
+ *
+ * Node.js 20+ enables autoSelectFamily by default, which tries IPv4 and IPv6
+ * simultaneously. When connections fail, it throws AggregateError which older
+ * HTTP libraries don't handle properly.
+ *
+ * See: https://github.com/yagop/node-telegram-bot-api/issues/1193
+ *      https://github.com/nodejs/node/pull/46790
