//! Integration tests for the packaging rule's foundation (#70): exercise the
//! `packaging::scan` library API over fixture "artifact" trees. The rule (README
//! "Packaging"): test files must never ship in a built artifact. Each fixture
//! stands in for an unpacked built artifact (a wheel, a `dist/`).
//!
//! The e2e suite (`packaging_e2e.rs`) drives the same fixtures through the built
//! binary; this checks the library contract directly.
