Servers advertise many addresses (public, relay, LAN, Docker bridges).
Use the last one that worked and race the rest only if it fails. Friends'
servers that keep failing back off exponentially instead of slowing
every poll. Errors now name each server and the underlying cause, e.g.
"blackcoffee: ECONNREFUSED", instead of undici's generic "fetch failed".
