Add test coverage for nameserver processing limits
Introduce a new system test (nsprocessinglimit) to verify that the
resolver strictly respects outgoing network fetch quotas when presented
with heavily delegated, unresponsive zones.

This test acts as a regression check for the recent Fisher-Yates nameserver
selection refactor.  It sets up an authoritative server delegating a zone
to 23 distinct nameservers (all pointing to unresponsive loopback IPs).

Using dnstap, the test forces a resolution failure and verifies that:
1. The resolver successfully traverses the zone delegation path.
2. The resolver caps the outgoing network queries to the delegated
   nameservers exactly at the processing limit (20 fetches), ensuring
   array boundaries and dynamic fetch quotas are strictly enforced without
   crashing or hanging.
