Subject: [PATCH] feat(ci): expose guest-cpu/guest-memory-mb; ns7zip Linux 8GB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

job.py already patches the clone VMX (numvcpus/memsize) via
--guest-cpu/--guest-memory-mb; expose them as action inputs
(default '0' = keep template). build-ns7zip.yml sets
guest-memory-mb: 8192 — the parallel MinGW cross-compile thrashes at
the 4 GB Linux template default (Windows template is 6 GB).
