…ache tun2proxy operates at the network level and sends SOCKS5 CONNECT with resolved IPs, losing the original hostname. This causes approval messages to show IPs instead of hostnames and hostname-based policy rules to miss. Add ReverseDNSCache that populates from DNS response A/AAAA records as they pass through sluice's DNS interceptor. The SOCKS5 handler uses this cache to recover the hostname before policy evaluation, so Telegram approval messages show "auth.openai.com:443" instead of "172.64.146.15:443" and hostname-based allow/deny rules match correctly.
