Add optional DoH support to encrypt all post-analysis DNS lookups (forward and reverse) via HTTPS instead of plaintext UDP/TCP DNS. When enabled, all calls to resolve() and reverse DNS in _enrich_hosts() route through a configurable DoH provider (default: Google). This prevents DNS query leakage from the analysis host. Configuration in cuckoo.conf [processing] section (same as reverse_dns): dns_over_https = yes doh_url = https://dns.google/resolve Compatible with any provider supporting application/dns-json: - Google: https://dns.google/resolve (default) - Cloudflare: https://cloudflare-dns.com/dns-query - Custom/self-hosted DoH resolvers Changes: - lib/cuckoo/common/dns.py: Add resolve_doh(), set_doh(), set_doh_url() with requests.Session for connection pooling, rdtype-aware response filtering, HTTPS URL validation, and specific exception handling - modules/processing/network.py: Read config, use DoH for PTR lookups, normalize trailing dots in both DoH and non-DoH PTR paths
