LatencyCheck (latency.py) runs one ping -c 1 -W 1 subprocess per catalog entry, sequentially. Every unreachable server costs a full second, so a populated catalog takes minutes to settle - and it runs at startup, after every import, and on every network change.

Two independent fixes, one feature:

Parallelize: ~30 pings in flight (thread pool or asyncio subprocesses, no new dependency) turns minutes into seconds.
Dedupe by IP: entries sharing an address are pinged once each today. The ProtonVPN WireGuard siblings (#196) doubled that provider's ping count for zero information - each rides the same EntryIP as its OpenVPN twin. Ping unique IPs, fan the result out to every entry sharing one.

Worth keeping: the previous-fastest-first ordering (sort_by_latency), so the visible top of the list settles first while the long tail fills in.
