fix(rebuild): re-index and purge the CDN after a rebuild (#160)
## Problem

The rebuild now works — `AATtools 0.0.3` was detected as a source fallback, built, and published:

```
ℹ `upload_single_binary()`: Replacing the CRAN source published for AATtools 0.0.3 … with the binary.
✔ Successfully uploaded package AATtools with tag 0.0.3.
```

But clients still get the source, and will for about a year:

```
$ curl -sI .../src/contrib/AATtools_0.0.3.tar.gz
etag: "ea8127d953ca6a2f118ea49441772af6"   # CRAN's source MD5
cdn-cache: HIT
cdn-cachedat: 08/09/2026 16:43:32          # predates the 18:12 upload
```

Two causes, both specific to a rebuild:

1. **The slot is never re-indexed.** `weekly-rebuild-missing` has no `upload_package_index` step, so the index keeps the old MD5 and — for anything that had been served from source — no `Built` stamp. This one self-heals at the next `process-updates` run.
2. **The tarball URL is never purged.** A normal update publishes new packages at *new* URLs, so `purge_cdn_cache.sh` only needs the five index files. A rebuild replaces an object *in place*, and the zone caches tarballs for `cache_expiration_time = 31919000` (~370 days). This does not self-heal.

Nothing about a stale package looks wrong from the outside, which is what makes it worth fixing rather than documenting.

## What this changes

**Re-index at the end of a rebuild**, flat and per-minor, mirroring the tail of `process-updates`. The codename is detected from the image's `/etc/os-release` (as `local/packages-to-build.R` already does) rather than adding `OS_ID` to all 18 matrix rows.

**Purge the zone afterwards**, via a new `scripts/purge_cdn_zone.sh`. One call to `POST /pullzone/{id}/purgeCache` covers every replaced object, and all three hostnames — `cran.devxy.io`, `cran.allianceswisspass.devxy.io`, `cran.rpkgs.com` — share pull zone `3857050`, confirmed from the `cdn-pullzone` response header.

Purging per URL was the alternative and is worse here: ~13.5k rate-limited calls per arch, where a single missed call leaves a package silently stale. The cost of the zone purge is a cold cache for everything else, which is why it stays out of the daily update path — `purge_cdn_cache.sh` is untouched.

The purge runs on failure too (`when: status: [success, failure]`): a rebuild that died part-way still replaced objects, and those are exactly the ones a stale edge keeps hiding.

## Verification

`crow lint .crow/` reports all ten configs valid; `bash -n` on the new script passes; prek hooks pass.

Not yet exercised against Bunny — it needs `BUNNYNET_API_KEY`, which is a CI secret. The failure mode is explicit rather than silent: any status other than 200/204 prints the response body and exits non-zero.

# Consolidated weekly-rebuild-missing pipeline (all platforms, both arches).
# One matrix row per OS/arch replaces the former per-platform files.
# Routing is preserved 1:1:
# - cron: each existing `weekly-rebuild-missing-<os>-<arch>` cron fires only
# its matching matrix row (via the per-row `cron:` name filter).
# - manual: `weekly_rebuild_missing` dropdown, default "all" (matches the
# previous bare manual trigger that ran every os/arch); pick a
# single <os>-<arch> to run just one.
# Arch placement is handled by the group label (rpkgs-amd64, rpkgs-arm64).
variables:
# Gates this pipeline. A manual pipeline creation instantiates every file in
# .crow/, and a declared default is applied even when the run never passed
# this variable, so the default must be a value that matches no matrix row.
