//! Regression: WASM e2e `package.json` must point its local `file:` dependency at
//! `<wasm-crate>/pkg/nodejs`, not the parent `pkg/` directory.
//!
//! `wasm-pack build --target nodejs --out-dir pkg/nodejs` writes the actual
//! npm-consumable package (with its own `package.json` declaring `main`/`types`)
//! to `pkg/nodejs/`. The parent `pkg/` has no `package.json`, so pointing a pnpm
//! `file:` dependency at `pkg/` fails resolution and leaves the e2e suite unable
//! to import the binding.
