The cache address was detected once at startup, and the interface fallback ranked ethernet names above IPv4. A runner that started before DHCPv4 finished could advertise a global IPv6 address to IPv4-only job networks until it restarted, failing every artifact and cache call. IPv4 now ranks first, and the address is detected again for each job unless `cache.host` sets it. Detecting an IPv6 address logs a warning.
