Razvan Dimescu e4350ae81c feat: add DNS-over-TLS (DoT) listener (RFC 7858) ...

Refactor handle_query into transport-agnostic resolve_query that returns
a BytePacketBuffer, keeping the UDP path zero-alloc. Add a TLS listener
on port 853 with persistent connections, idle timeout, connection limits,
and coalesced writes. Supports user-provided certs or self-signed CA
fallback. Includes 5 integration tests.
