/**
 * Proves the Prime Agent runtime against the real endpoint.
 *
 * A typecheck cannot tell you that the credential resolved, that the loader was
 * reloaded, or that no built-in tool survived `noTools: 'all'` — every one of
 * those failures compiles perfectly and shows up as a 401, a coding-assistant
 * answer, or a shell in a CRM. So this asks the live model a question with a
 * seeded tool behind it and prints what actually happened.
 *
 *   corepack pnpm -F @pig/piggy exec tsx src/dev/verify-prime-agent.ts [modelId]
 *
 * Requires PRIME_API_KEY. It spends a few hundred tokens; it is a dev tool, not
 * a test, and nothing in CI runs it.
