Subject: fix IPv6 connection failures with Happy Eyeballs (RFC 8305)

Implement a custom WebSocketTransport that races IPv6 and IPv4 connections
with a 250ms head start for IPv6, matching browser behavior. This prevents
broken IPv6 from blocking all relay connections indefinitely.

This is a temporary fix until the upstream async-wsocket PR is merged:
