Extend the local cache stack with three independent capabilities:
1. Inner-`dockerd` build coverage for HTTP-only package mirrors.
`roles/sys-svc-compose/files/compose.py` (the runner's `compose`
wrapper) auto-generates a transient `compose.cache.override.yml`
per app when `INFINITO_PACKAGE_CACHE_FRONTEND_IP` is exported. The
override pins `build.extra_hosts` for `deb.debian.org`,
`archive.ubuntu.com`, and `security.ubuntu.com` to the frontend.
`pull.py` now delegates to the wrapper so build/pull operations see
the same `-f` set the wrapper auto-detects. nginx in the frontend
gains a port-80 listener with path rewrites for those hostnames,
and `package.sh` registers two new Nexus proxies
(`apt-debian-security`, `apt-ubuntu-security`) for the security
suites whose upstream URL prefix differs from the main archive.
Alpine is intentionally excluded from the inner-build extra_hosts:
3.18+ defaults to HTTPS, and inner-`dockerd` build containers do
not import the frontend CA. Routing apk through the frontend would
trip TLS verification.
2. General cache freshness env-var. `scripts/meta/env/cache/package.sh`
exports `INFINITO_PACKAGE_CACHE_MAX_AGE_MIN` (default `129600`,
i.e. 90 days). The bootstrap helper consumes it for every Nexus
proxy's `contentMaxAge`, `metadataMaxAge`, and
`negativeCache.timeToLive`, replacing the previous 1440-minute
literal. Lower the value when chasing fast-moving upstreams.
3. SPOT cache documentation at `docs/contributing/environment/cache.md`.
`compose.yml.md`, `variables.md`, the per-service READMEs, and
`requirements/012-...` now link to it instead of restating the
stack's behaviour. Net documentation lines drop substantially while
the cache page becomes the single user-facing reference.
Also: code-comment cleanup per `docs/contributing/documentation.md`
guidelines across all touched .py / .sh / .yml files. Multi-paragraph
docstrings, banner separators, and restate-the-obvious comments are
removed; one-line WHY comments remain where the rationale is not
already visible in the code.

Add a TLS-terminating reverse proxy in front of the Sonatype Nexus 3 OSS
pull-through cache so the `infinito` runner can hit upstream
package-manager URLs (pypi.org, registry.npmjs.org, rubygems.org,
repo.packagist.org, proxy.golang.org, dl-cdn.alpinelinux.org,
files.pythonhosted.org, raw.githubusercontent.com, codeload.github.com)
unchanged and still flow through Nexus.
Mechanism:
* scripts/docker/cache/package-frontend-certs.sh — host-side helper,
idempotently generates a dedicated CA + per-hostname leaf certs.
* compose/package-cache-frontend/upstreams.conf — nginx server-blocks
that match SNI per hostname and reverse-proxy onto the matching
Nexus repo path.
* compose/cache.override.yml `infinito.extra_hosts` — DNS-hijack so
the runner's clients resolve each upstream onto the frontend's
static IP.
* scripts/docker/cache/package-frontend-ca.sh — runner-side helper,
drops the CA into the system trust store post-startup so apt/pip/
curl/etc. accept TLS against the hijacked hostnames.
* cli/deploy/development/compose.py — orchestrates cert gen before
compose-up, CA install after health.
Scope today: runner-only. App-service Dockerfile builds executed by
the inner dockerd are NOT routed through the frontend; that requires
build-time CA injection and is deferred.
Also extends scripts/docker/cache/package.sh with five additional
Nexus proxies registered for transparent use: gem-proxy, go-proxy,
yum-rocky, yum-fedora, raw-packagist, raw-alpine, raw-codeload-github.
Refactor: move all cache services + runner-side cache mounts/depends_on/
extra_hosts from compose.yml into compose/cache.override.yml. Base
compose.yml now describes only the bare CI/runtime stack (coredns +
infinito). The override file is the single gate for the cache stack;
`profiles: ["cache"]` attributes and `--profile cache` flag emission
were redundant once file inclusion controls existence and removed
accordingly.
