Subject: [PATCH] ci: make env probes non-fatal, swap free for /proc/meminfo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pipeline #41 died with exit 127 on `free -h` — procps isn't in the
nix-ci image. New info() helper runs the command and ignores the exit
code, so missing tools no longer abort the build. Also switched to
/proc/meminfo since it's always available on Linux.
