- 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
