The Build Admin workflow's `npm ci` step started failing on every PR opened
since early May 2026 with:
fatal error: zim/archive.h: No such file or directory
#include <zim/archive.h>
@openzim/libzim is a native Node module that compiles against the system
libzim C++ library via node-gyp. Builds were green through 2026-05-04 because
the ubuntu-latest runner image included libzim-dev preinstalled. Sometime
between 2026-05-04 and 2026-05-05 the runner image stopped shipping it, and
every admin PR since has failed at the libzim compile step.
Cuyua9's #733 (kiwix self-heal) and chriscrosstalk's #832 (vendor-aware AMD
HSA override) both hit this at 14:16 UTC and 16:01 UTC on 2026-05-05.
Fix: add an apt step that installs libzim-dev before `npm ci` runs.
