The URL test history update hook and the Clash mode update hook were
single-slot: the API service's attached service overwrote the hook set
by the daemon, so clients stopped receiving group updates. Replace both
with multicast hook lists.
Also share a single URL test history storage via context: Clash API
looked it up under a key nobody registered and fell back to its own
empty storage, so dashboards showed no delay once an API service was
configured. Selector changes now notify through the shared storage,
covering selections made from any API surface.
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.
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.
