kevinveenbirkenbachandClaude Opus 5 f9dea42c68 fix(package-cache): survive a flaky apt mirror

A debian:bookworm workspace job died on `apt-get update`: the mounted
sources list carried the Ubuntu entry too, Nexus had auto-blocked
archive.ubuntu.com, and apt fails the whole update on one bad source.

Three holes, three plugs:

- One sources list per INFINITO_DISTRO under compose/package-cache/apt/,
  selected by the compose overrides. A Debian runner no longer fetches
  an Ubuntu suite it has no use for. The non-apt distros get an empty
  file so the bind mount has a source to point at.
- autoBlock off. While a remote is auto-blocked Nexus answers `404
  Remote Auto Blocked` to every client instead of falling back to the
  copy it already has cached.
- Mirror failover in the frontend. Every apt suite gets a second proxy
  repo on an independent upstream; a 5xx from the primary re-runs the
  request against it. Nexus has no group repository type for apt, so
  the retry lives in nginx.

Measured on a live Nexus 3.91.1: dead remote without a cached copy
answers 502, with a cached copy 200 regardless of metadataMaxAge. The
frontend serves 149 kB of real bookworm `Release` from the mirror repo
when the primary is dead, and the new regex locations produce upstream
request lines byte-identical to the `rewrite … break` form they replace,
including `%3a` epochs in pool paths.

INFINITO_CACHE_PACKAGE_APT_LIST is gone; the mount interpolates
INFINITO_DISTRO directly.

README.md

utils/env 📐

This directory hosts the Python implementation behind make dotenv. For the general rules that govern READMEs in code directories see documentation.md. For the per-variable defaults that this code consumes see default.env.

Purpose 🎯

The package converts the committed default.env plus a small runtime context into the gitignored .env at the repo root. Every module here belongs to one of four roles: parse, resolve, orchestrate, write.

Structure 🗂️

File	Role
`parser.py`	Read default.env into `(values, comments)` tuples.
`runtime.py`	Resolve host-context lookups (disk, RAM, hostname, GHA/Act flags, `/proc/version`, helper-script invocation).
`builder.py`	Thin orchestrator that defines `EnvBuilder`, `BuildContext`, and `build_env()`. Walks the handler registry.
`writer.py`	Serialise an `EnvBuilder` into a docker-compose-compatible `.env` on disk.
`handlers/`	One module per dynamically-computed variable. See handlers README.

The CLI entry point lives at __main__.py under cli/meta/env/. Shell consumers source load.sh under scripts/meta/env/.

File Naming 🏷️

Module names MUST stay lowercase snake_case.
Pure passthrough or simple parser/writer helpers MUST live directly under utils/env/.
Per-variable computation MUST live under handlers/ (see handlers README for the naming convention used there).
Test files live in tests/unit/utils/env/ and mirror the module name with a test_ prefix.

Import Rules 🔗

parser.py, runtime.py, and writer.py MUST NOT import from builder.py or handlers/.
builder.py MUST NOT import individual handler modules; it MUST go through the ORDERED_HANDLERS list exposed by handlers/__init__.py.
Handler modules MUST NOT import each other (see handlers README).
