test: register four finding-count tests in touchfiles + tier map

Each new test depends on its skill template, the runner, and three
preamble resolvers (preamble.ts, generate-ask-user-format.ts,
generate-completion-status.ts) — those affect question cadence and
completion rendering, which is exactly what the test asserts on.

All four classified periodic. Sequential execution during calibration;
opt-in to concurrent only after measured comparison agrees (plan §D15).

Updated touchfiles.test.ts: plan-ceo-review/** now selects 19 tests
(was 18) because plan-ceo-finding-count joins the family.
