KKRainbow ed8df2d58f prevent EasyTier-managed IPv6 from being used as underlay connections (#2181)
When a node has public IPv6 addresses allocated by EasyTier, those addresses
are installed on the host's network interfaces. The system would then pick
them up as candidate source/destination addresses for underlay connections
(direct peer, UDP hole punch, bind addresses), causing overlay traffic to
loop back into the overlay itself.

Add a central predicate is_ip_easytier_managed_ipv6() and apply it at every
point where IPv6 addresses are selected for underlay use:
- Filter managed IPv6 from DNS-resolved connector addresses, including a
  UDP socket getsockname check to detect whether the OS would route through
  the overlay to reach a destination
- Skip managed IPv6 in bind address selection and STUN candidate filtering
- Strip managed IPv6 from GetIpListResponse RPC so peers never learn them
- Pass pre-resolved addresses to tunnel connectors to avoid re-resolution

fanyang cf6dcbc054 Fix IPv6 TCP tunnel display formatting (#1980)
Normalize composite tunnel display values before rendering peer and
debug output so IPv6 tunnel types no longer append `6` to the port.

- Preserve prefixes like `txt-` while converting tunnel schemes to
  their IPv6 form.
- Recover malformed values such as `txt-tcp://...:110106` into
  `txt-tcp6://...:11010`.
- Reuse the normalized remote address display in CLI debug output.

KKRainbow 28cd6da502 Add fake tcp tunnel (experimental) (#1673)
support faketcp to avoid tcp-over-tcp problem.
linux/macos/windows are supported.

better to be used in internet env, the maximum 
performance is majorly limited by windivert/raw socket.
