feat(edge): route PACKAGES requests to the per-R-minor slot
- add edge/rpkgs-router.ts, which redirects PACKAGES, PACKAGES.gz and
  PACKAGES.rds into …/src/contrib/<x.y>/ for slots listed in UNION_SLOTS
- leave tarballs alone: R keeps the pre-redirect contrib URL, so the union
  index steers per-minor tarballs with a Path field instead
- stop resolving an unidentifiable distro to a phantom linux-gnu/linux-musl
  slot and send those clients to CRAN
- mark every redirect no-store, since the target depends on the User-Agent
- cover the routing matrix in edge/rpkgs-router.test.ts, run by just edge-test
- correct the spec and plan: the union index carries Path: <x.y> on per-minor
  records, not Path: .. on flat ones

# Local helpers for build-cran-binaries.
#
# `rebuild` (re)builds specific versions of a single package on a given OS/arch
# by dispatching to a remote buildx builder (the build runs there, not locally).
# Sensitivity is auto-detected: risky packages land in the per-minor slot
# (contrib/<x.y>/), everything else in the generic slot; the touched index is
# refreshed so the result is immediately servable.
#
# Prerequisites:
# - buildx builders named `artemis` (amd64) and `gaia` (arm64), created with the
# docker-container driver (runs BuildKit on the remote host's docker daemon over
# SSH). The default `remote` driver does NOT work with an ssh:// docker host.
# Pass --config docker/buildkitd.toml so BuildKit's GC keeps a usable cache
# (the default caps the cache-mount tier at 512 MB, forcing re-downloads).
# docker buildx create --name artemis --driver docker-container --config docker/buildkitd.toml ssh://<user@host-amd64>
# docker buildx create --name gaia --driver docker-container --config docker/buildkitd.toml ssh://<user@host-arm64>
# - exported secrets: B2_S3_ACCESS_KEY, B2_S3_SECRET_KEY, PGPASS (GITHUB_PAT optional)
#
# Overridable (env or `just VAR=… rebuild …`):
# R_VERSION (default 4.5.3) — selects the R minor → the per-minor slot
# AMD64_BUILDER / ARM64_BUILDER — buildx builder names
#
# Examples:
# just rebuild alpine 3.23 amd64 rlang 1.1.4 1.1.3
# just rebuild redhat 10 arm64 data.table 1.15.4
# R_VERSION=4.4.3 just rebuild ubuntu noble amd64 Rcpp 1.0.12
