260312 mem from cgroup over sys#22

lists:max over {Ratio, Total} tuples picks the highest ratio, which is
misleading in containers: the host /proc/meminfo view can show >70% while
the cgroup limit (what actually constrains the process) is <10%, or vice
versa. Try cgroup2 first, then cgroup v1, then fall back to host sys only
when neither cgroup interface is readable.
Bump appup top to 0.3.6 and add load_module instructions for lc_lib across all listed upgrade/downgrade paths (the cgroup-preference fix touches only lc_lib). app.src vsn remains "git"; check_vsns.escript will need to be revisited at tag time.
vsn = "git" is a rebar3 sentinel that resolves to the git tag at build time. check_vsns.escript reads the literal source, so it would always fail in development between releases. Treat "git" as a pass-through and only enforce equality when app.src carries a concrete version.
