DNS rules referencing rule-sets that contain only ip_cidr predicates
silently stopped matching when legacy DNS mode was disabled, because the
IP-CIDR branch cannot match against an in-flight DNS query. The existing
validation intentionally let every rule_set through on the premise that
mixed sets still work via their non-IP branches, which is only true when
such a branch exists. Track whether a rule-set carries any non-IP-CIDR
predicate and reject pure-IP references the same way bare ip_cidr fields
are already rejected.
Inverted rules whose address filter conditions come from rule sets or
logical rules were rejected during pre-lookup matching, so the lookup was
never sent and the rules never matched; for plain ip rule sets this was a
regression from the rule-set invert fix in 1.12.22. Pre-lookup matching
now tracks whether the result depends on deferred address filter
conditions and defers such rules to the response phase, while results
already determined by evaluated conditions are still decided during
pre-lookup.
Align dev-next-grpc with wip2 by adding UsePlatformWIFIMonitor()
to the new PlatformInterface, allowing platform clients to indicate
they handle WIFI monitoring themselves.
The cache lookup was performed before rule matching, using the caller's
strategy (usually AsIS/0) instead of the resolved strategy. This caused
cache misses when ipv4_only was configured globally but the cache lookup
expected both A and AAAA records.
Remove LookupCache and ExchangeCache from Router, as the cache checks
inside client.Lookup and client.Exchange already handle caching correctly
after rule matching with the proper strategy and transport.
