- Flutter: Hide 'DNS Server' field and force '10.1.0.1' if connection link contains owndns=true
- Flutter: Remove 'Use Provider DNS' toggle to eliminate client-side choice
- Server (relay.rs): Intercept DNS queries targeting '10.1.0.1:53' and process them via internal DnsServer if DNS is enabled
- Server (api.rs): Continue appending owndns=true to subscription links to enforce internal DNS logic on clients
- ostp-server/relay.rs: remove DNS port 53 interception — DNS queries
now pass through to the actual DNS server as regular TCP connections
- ostp-client/native_handler.rs (Windows): add explicit gateway/32 route
via real interface BEFORE setting default route via TUN to prevent loop
- ostp-client/native_handler.rs (Linux): properly detect real gateway and
add default route via TUN with metric 10 after server IP exclusion
- Remove redundant extra DNS host routes from Windows setup script
