mirrors are attempted to ipv6 and fails, wget waits too long for retry

Tested with ./docker_local_dev.sh modified flake.nix ``` # Git configuration for safe directory access. echo -e '[safe]\n\tdirectory = *\n' > /root/.gitconfig + + # Prefer IPv4 over IPv6 for wget/curl downloads + echo "precedence ::ffff:0:0/96 100" > /etc/gai.conf + + # Set shorter timeout for wget + echo "timeout = 10" >> /etc/wgetrc ''; }; ```
