The SSRF guard only checked the host string, so an attacker-owned domain
resolving to 169.254.169.254 / 10.x (DNS rebinding, TOCTOU) bypassed it.
Add a reqwest dns::Resolve (SafeResolver) that drops resolved addresses in
private ranges, wired into all four crawler/analysis clients — it fires per
connection so it also covers redirect hops. Also close the is_private_ip
IPv6-embedding gaps (IPv4-compatible ::/96, NAT64 64:ff9b::/96, 6to4
2002::/16 all now unwrap to the embedded IPv4).
Bump to 0.124.10.
