Introduce max-delegation-servers configuration option
Make the maximum number of processed delegation nameservers configurable
via the new 'max-delegation-servers' option (default: 13), replacing the
hardcoded NS_PROCESSING_LIMIT (20).

The default is reduced to 13 to precisely match the maximum number of
root servers that can fit into a classic 512-byte UDP payload.  This
provides a natural, historically sound cap that mitigates resource
exhaustion and amplification attacks from artificially inflated or
misconfigured delegations.

The configuration option is strictly bounded between 1 and 100 to ensure
resolver stability.
