Razvan Dimescu be60f6ccbc chore(packaging): docker-compose + Caddyfile for ODoH relay deploy ...

Two-container deploy: Caddy terminates TLS (auto-provisions Let's
Encrypt via ACME) and reverse-proxies to a Numa relay on an internal
Docker network. The relay never reads sealed payloads; Caddy's
access log is discarded so per-request observability doesn't defeat
the oblivious property.

Validated against Hetzner CX22 + DNS at odoh-relay.numa.rs:
- TLS-ALPN-01 challenge succeeded on first attempt
- /health returned the relay's counter block
- End-to-end ODoH client → relay → Cloudflare works

Operators only need to: set a DNS A record, edit Caddyfile's hostname,
docker compose up -d. README walks through the steps and the DNSCrypt
v3/odoh-relays.md submission to claim a public listing.
