Move plausible from weekly to external in used-recipes.md. cc-ci still
deploys/tests it (the recipe + tests stay enrolled, !testme bridge
unchanged), but it is no longer surveyed/upgraded by the weekly /upgrade-all
run — maintained elsewhere, like uptime-kuma.
The open plausible PR #5 (clickhouse 23.4.2.11 -> 23.4.6.25) from this week's
run stays open for the operator; no future weekly PRs will be opened for it.
Operator: uptime-kuma is maintained elsewhere — drop it from the weekly upgrade
but keep it in the used-recipes inventory. New cc-ci-plan/used-recipes.md is the
canonical list of every recipe cc-ci deploys/tests, with a weekly|external tier;
upgrade-all §1 now excludes 'external' rows from the candidate list (explicit
--args still override). uptime-kuma = external; all others weekly.
