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.

- document docs README purpose and scope in a dedicated SPOT
- add scope-focused README.md files across docs directories
- remove lint rule that banned README.md files under docs
Replace per-directory README.md index files with automatic glob toctree
in root index.rst (docs/**). Add lint test that fails if any README.md
appears under docs/. Document the no-README rule in documentation.md.
