Introduces a `registry-cache` service (rpardini/docker-registry-proxy) in
the `ci` profile that MITM-caches every outbound docker registry pull
made by `infinito`'s inner dockerd, drastically cutting bandwidth on
re-deploys, parallel CI shards, and local fresh-purges.
Wiring (all bind-mounted via compose.yml, no Dockerfile or entry.sh
staging, so edits hot-reload on next container start):
- CA bundle at /opt/registry-cache-ca (read-only),
- systemd drop-in at /etc/systemd/system/docker.service.d/registry-cache-proxy.conf,
- registry-cache-ca.sh at /usr/local/bin/registry-cache-ca.sh.
The drop-in registers registry-cache-ca.sh as ExecStartPre. Compose
gates `infinito` on `registry-cache` `service_healthy` so the CA is on
disk before dockerd boots; the install script supports both Debian
(`update-ca-certificates`) and Arch/Fedora (`update-ca-trust extract`)
trust stores, detected by command availability.
Also reorganizes compose/ into per-service subdirectories
(compose/coredns/, compose/registry-cache/) with README.md per directory
following the documentation guidelines, adds scripts/docker/README.md,
and nests the registry-cache host paths under /tmp/infinito/core/
(mirror/ for blobs, ca/ for the MITM CA bundle).

- Introduce env.ci as single source of truth for CI networking
- Make docker-compose, CoreDNS and Docker daemon fully env-driven
- Render CoreDNS Corefile from template via envsubst
- Replace hardcoded IPs/domains with environment variables
- Integrate env-based networking into Ansible defaults
- Remove static Corefile and daemon.json
This makes DNS and networking deterministic and reproducible across
host, CoreDNS, infinito runner and Docker-in-Docker.
