Add formulas/run-user-test.toml — a sense-only process definition for
persona-based UX evaluation. Defines 5 personas across 2 funnels
(passive-holder: tyler/alex/sarah; staker: priya/marcus), full stack
lifecycle (start → run → collect → stop → deliver), and the three
standard evidence delivery products (evidence JSON committed to main,
screenshots referenced in evidence, summary as issue comment).
