fix: restore CNAME chain caching in DNS dispatcher (issue #250)

Replaces the naive exact name+type answer filtering with a CNAME-aware
extractAnswersForQuestion function that follows CNAME chains to collect
all relevant records. This restores CNAME chain caching while preserving
multi-question isolation (issue #225).

- Add extractAnswersForQuestion helper that follows CNAME chains up to 8
  levels and collects CNAME records, exact type matches, and A/AAAA
  records for CNAME targets
- Fix false-positive CNAME cache hit test (upstream was still running
  during the 'cache hit' check; now directly verifies cache contents and
  shuts down upstream to prove cache hit)
- Add multi-level CNAME chain test (A -> B -> C -> IP)
- Add benchmarkCacheHitCNAME benchmark
