queried address family has no range configured. Reject configurations
where neither inet4_range nor inet6_range is set.

The TTL computation and assignment loops treat OPT record's Hdr.Ttl
as a regular TTL, but per RFC 6891 it encodes EDNS0 metadata
(ExtRCode|Version|Flags). This corrupts cached responses causing
systemd-resolved to reject them with EDNS version 255.
Also fix pointer aliasing: storeCache() stored raw *dns.Msg pointer
so subsequent mutations by Exchange() corrupted cached data.
- Skip OPT records in all TTL loops (Exchange + loadResponse)
- Use message.Copy() in storeCache() to isolate cache from mutations

Treat rule_set items as merged branches instead of standalone boolean
sub-items.
Evaluate each branch inside a referenced rule-set as if it were merged
into the outer rule and keep OR semantics between branches. This lets
outer grouped fields satisfy matching groups inside a branch without
introducing a standalone outer fallback or cross-branch state union.
Keep inherited grouped state outside inverted default and logical
branches. Negated rule-set branches now evaluate !(...) against their
own conditions and only reapply the outer grouped match after negation
succeeds, so configs like outer-group && !inner-condition continue to
work.
Add regression tests for same-group merged matches, cross-group and
extra-AND failures, DNS merged-branch behaviour, and inverted merged
branches. Update the route and DNS rule docs to clarify that rule-set
branches merge into the outer rule while keeping OR semantics between
branches.
