patternihaandClaude Opus 5.5 2933b0c8d5 TUN inbound: Don't warn that loopback DNS servers are blocked
With autoSystemWfpBlockLeak, loopback now always stays allowed, so a DNS
server in dns like 127.0.0.1, a local resolver, stays reachable although
it lies in neither gateway nor autoSystemRoutingTable. Leave loopback
servers out of the warning that queries to them cannot go through the TUN
and are blocked, and say so in the README.

patternihaandClaude Opus 5.5 bb4cd4b6d3 TUN inbound's autoSystemWfpBlockLeak: Add "allexceptlan"
"allexceptlan" is "all" but for the local network: traffic to and from
private (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, fc00::/7), link-local
(169.254.0.0/16, fe80::/10), multicast (224.0.0.0/4, ff00::/8) and broadcast
(255.255.255.255) addresses stays allowed, so that printers, the router's
settings page, or casting to a TV keep working while nothing else leaves
outside the TUN.

It includes "dns": a resolver on the local network, like the router's,
would forward the queries outside the TUN, so DNS stays blocked there. The
LAN permit sits below the other values, like the permit through the TUN, so
they still apply on the local network, e.g. "tcp/445" blocks Windows file
sharing with it. The DNS Client service keeps mDNS and LLMNR, to the local
network's addresses only. "all" overrides it.

The addresses are matched with FWP_V4_ADDR_MASK and FWP_V6_ADDR_MASK
conditions on the remote address, which match when any of them does.

patternihaandClaude Opus 5.5 468f745fc2 TUN inbound's autoSystemWfpBlockLeak: Add "all", "tcp", "udp", "icmp" and port ranges; Always allow loopback, DHCP and IPv6 neighbor discovery
autoSystemWfpBlockLeak now also takes:

- "all": everything outside the TUN, IPv4 and IPv6, in both directions, so
  nothing but Xray leaves except through the TUN.
- "tcp", "udp": all ports of that protocol, also written "tcp/0", "udp/0".
- "tcp/<low>-<high>", "udp/<low>-<high>": a range of ports, matched with
  FWP_MATCH_RANGE, as two conditions on the same field would match when
  either does.
- "icmp": ICMP and ICMPv6, e.g. ping. It takes no port: in ICMP filters the
  local port holds the type, and "icmp/0" would read as the echo reply.

Values are normalized: "tcp/0" and "tcp/1-65535" become "tcp", and
"tcp/53-53" becomes "tcp/53".

Whatever is blocked, loopback, which cannot leave the system, and what
Windows itself needs on the local link now always stay allowed: DHCP, DHCPv6,
and IPv6 neighbor and multicast listener discovery. These used to be allowed
only along with "misconfigtun", so "udp" or "icmp" would otherwise have cut
DHCP or IPv6 neighbor discovery, and "tcp" any local proxy, Xray's own
inbounds included. Loopback being allowed means that with "dns", a local
resolver on 127.0.0.1:53 now works for other programs (its own queries to
port 53 or 853 outside the TUN stay blocked), and the DNS Client service
may use it.

"all" reuses the filters of "misconfigtun", which now also let everything
through the TUN, for both IP versions whatever the routes.

On other TUN options: keeping the system's DNS inside the TUN, with "all",
"dns", "windnsclient", or anything covering TCP or UDP port 53 ("udp",
"tcp/50-60", ...), needs dns, as Windows can no longer reach the DNS
servers of the other interfaces; the config is rejected otherwise. Like the
other values, the new ones need autoSystemRoutingTable. The filters do not
need autoOutboundsInterface, as Xray is allowed by its app ID; it still
keeps Xray's own connections out of the TUN's routes.
