fix: force IPv4 DNS in Squid proxy to fix proxy test failures

mridang · claude · mridang · commit 1113be37d1fe · 2026-04-13T11:42:56.000+07:00
Squid resolves host.docker.internal to an IPv6 address, but Docker
port mappings only listen on IPv4, causing ERR_CONNECT_FAIL (101)
Network is unreachable. Adding dns_v4_first forces IPv4 resolution.
