Improved Domain Connection Features for Repl

The existing domain verification method directly called Replit proxy paths, which placed a heavy load on servers, but it has now been changed to a method that first checks DNS records, increasing efficiency. In addition, TXT record verification has been added so that connections can be made while maintaining the protection features of services like Cloudflare.

A separate proxy was built for Apex domain (e.g., replit.com) connections. Previously, there were difficulties due to CNAME record limitations, but now the location of the Repl is identified through a TXT record, and it works smoothly even on Apex domains by using an A record.

Through the Magic domain connection feature, users can use their own domain without a repl.co subdomain. By setting a specific TXT record (replit-user=username) and an A record for the proxy (34.132.134.162), all Repls can be used immediately on that domain.

Finally, multiple domain connection is supported, allowing several domains to be connected to a single Repl. Each domain has an independent verification process and status.
