//! Pure-Rust DNS for scratch containers (Hickory resolver, no `getaddrinfo`).
//!
//! | Traffic | Resolver |
//! |---------|----------|
//! | Outbound HTTPS (reqwest) | [`https_client`] / [`reqwest_resolver`] |
//! | AetherDB wire (`tcp://host:port`) | [`resolve_tcp_connect`] |
//! | Embedded AetherDB (`local` / unset URL) | None — no DNS |
//!
//! Configure upstream nameservers with **`NAUTALID_DNS`** (comma-separated IPs). When unset,
//! Hickory reads **`/etc/resolv.conf`** if the runtime injects it; otherwise falls back to
//! public resolvers with a warning. Optional warm-up probe: **`NAUTALID_AETHER_CONNECT`**.
