kevinveenbirkenbachandClaude Opus 4.7 1dd8d3f5c0 feat(compose): add pull-through registry-cache + reorg compose/ subdirs
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).

# Compose Configuration 🧩
This directory holds the static configuration assets consumed by the
top-level [compose.yml](../compose.yml) of the local development and CI
testing stack.
## Scope 📋
- The directory MUST contain only files that are bind-mounted into a
service defined in `compose.yml`.
- The directory MUST NOT host application configuration that belongs to
an Ansible role. Per-role compose payloads live under
`roles/<role>/templates/`.
- The directory MUST NOT host workflow scripts, test fixtures, or
build helpers. Those belong under `scripts/` or `tests/`.
## Layout 🗂️
Each compose service that needs static configuration owns a
sub-directory whose name matches the service. New service-specific
config MUST go into the matching sub-directory rather than at the
`compose/` root.
For the rules that govern `compose.yml` itself (env-variable contract,
profile gating, resource caps), see
[compose.yml.md](../docs/contributing/artefact/files/compose.yml.md).
