//! Integration tests for the TypeScript packaging slice (#73): exercise the
//! `packaging::inspect` library API over the pre-built `npm pack` **tarball**
//! fixtures (`.tgz`). Rule (README "Packaging"): test files must never ship in
//! the built artifact.
//!
//! The e2e suite (`packaging_npm_e2e.rs`) drives the same tarballs through the
//! built binary; this checks the library contract — `inspect` unpacks the
//! gzipped tar and reports offenders relative to the artifact root.
