/**
 * Smoke test for ADR-131 / ruvnet/ruflo#2149 — ToolOutputGuardrail wired up
 * end-to-end through the published `@claude-flow/security` build output.
 *
 * Runs after the security package has been built (CI: `Build V3` job). This
 * is the "real install" check that catches:
 *   - the class missing from `dist/index.js` exports
 *   - regressions in the four canonical ASI01 attack patterns
 *   - changes to the default policy mapping that would silently weaken
 *     production deployments
 *
 * The exhaustive behavioural surface lives in the package's vitest suite
 * (`__tests__/tool-output-guardrail.test.ts` — 24 tests, runs in <1s).
 * This smoke is intentionally tiny and fast (<300 ms) so it can be wired
 * into the supply-chain / build-artifact lane without dragging in the full
 * test runner.
