🐛 Fix container DNS: ship resolv.conf without search domain 🐛

Browse Source 
Hosts with a search domain cause containers to inherit it. When the
zone has a wildcard AAAA record, public hostnames resolve to the host's
own IPv6 address instead of the real server, breaking all outbound
HTTPS and DNS from inside the container.
The entrypoint already has a hook: if /usr/local/etc/resolv.conf
exists it replaces /etc/resolv.conf at container startup. Ship a
clean resolv.conf with Cloudflare + Google DNS and no search domain
so container DNS is always correct regardless of host configuration.
- rootfs/usr/local/etc/resolv.conf: new file — clean DNS, no search domain

rootfs/usr/local/etc/resolv.conf
