Fixes connectivity issues when services are listening on IPv6 loopback addresses (::1) by implementing IPv6-preferred DNS resolution for localhost. Changes: - Add custom HTTP/HTTPS agent for localhost that prefers IPv6 addresses - Implement DNS lookup that checks both IPv6 and IPv4, preferring IPv6 - Automatic fallback to IPv4 when IPv6 is not available The fix ensures the REST Client can connect to services regardless of whether they're bound to IPv4 (127.0.0.1), IPv6 (::1), or both. Fixes Huachao#1145

Fixes #1145
Problem
Many modern dev servers (Node.js v18+) bind to IPv6 by default. When a service only listens on

Add IPv6-preferred DNS resolution for localhost requests. The extension now:
