test: structural Design count boundary; TODO proposals are not findings

Replaying run 36385945043 through the Design count predicates: routing,
focus and learnings setup was not recognized as setup, Issue 1 was counted
pre-review in both attempts (the boundary fired on it), and attempt 2
counted the Font TODO proposal as a finding (review=4 and review=5 for five
issues). The paid caller now starts review at the first answered native
decision that is not setup (recognized packet, or setup header/question ID),
a completion handoff, artifact rendering or a TODO proposal (the review's
Add to TODOS.md / Skip / Build it now menu). TODO proposals are recorded as
administrative extra decisions. The replay asserts each counted call: both
attempts review=5 (Issues 1-5). isDesignCountFirstReview and its controls
are unchanged.
