This PR implements all the dialers and resolvers needed to make pre-checks happen. So this task focuses on the following: 1. Implement the DNS probe: call DNSResolver.Resolve(region) 2. Implement the QUIC probe: call QUICDialer.DialQuic (handshake only, no stream opened) and record the result. 3. Implement the HTTP/2 probe: call TCPDialer.DialEdge (TCP + TLS handshake only, no frames sent) and record the result. 4. Implement the Management API probe: call ManagementDialer.DialContext to api.cloudflare.com:443 and record the result. 5. Export edgeDiscovery as EdgeDiscovery in edgediscovery/allregions/discovery.go so the pre-check can reuse the production DNS path. This sets up the main components to implement the checker.
