Six personas in two sets: customer, operator, competitor (product) + architect, engineer, future-claude (OS/engine)
Auto-inference: OS signals in idea → architect, else → customer
Named shortcuts: npm run skeptic:customer, :operator, :competitor, :architect, :engineer, :future-claude
Help command: npm run skeptic -- help
