📄 Description

Describe your changes

Rewrite prepareURL in the relay WS dialer to use net/url parsing instead of a strings.Replace based scheme rewrite, and add tests covering non-standard ports and other edge cases.

Parse the relay address with url.Parse, switch on the scheme, and set the path explicitly
Add table-driven tests for ports, IPs, hostnames starting with rel, and rejected schemes
