Johnathan Corgan 4a882ab591 TUN fd00::/8 route fix, two-node example updated from live testing ...

Add fd00::/8 route to TUN configure_interface() via rtnetlink - without
this route the kernel had no path to FIPS addresses ("network unreachable").

Update two-node-udp README based on live namespace testing:
- Remove resolvectl steps (doesn't work inside namespaces)
- Remove ICMPv6 Echo Reply mention (kernel handles it natively)
- Add namespace DNS limitation note and kernel ping reply explanation
- Simplify from 8 to 7 steps
