[BUG]: Cannot find module `@stdlib/lapack` under pnpm

[softcraft-development]

Description

I have a brand new & largely empty package where I installed @stdlib/stdlib (^0.3.0). To get started I wrote the following test in vitest:

import * as s from "@stdlib/stdlib"
import { describe, expect, it } from "vitest"

describe("stdlib", () => {
  it("loads the library", () => {
    expect(s).toBeDefined()
  })
})

Running the test generates this error:

Error: Cannot find module '@stdlib/lapack'
Require stack:
- [root]/node_modules/.pnpm/@stdlib+stdlib@0.3.0/node_modules/@stdlib/stdlib/lib/main.js
- [root]/node_modules/.pnpm/@stdlib+stdlib@0.3.0/node_modules/@stdlib/stdlib/lib/index.js
 ❯ Object.<anonymous> ../../node_modules/.pnpm/@stdlib+stdlib@0.3.0/node_modules/@stdlib/stdlib/lib/main.js:190:32

Indeed, lapack is not installed at that location, nor is it in any other location in my project.

Note that I'm using pnpm as my package manager. I'm not certain whether this is a significant issue or not. The command I used to install stdlib was very standard: pnpm add @stdlib/stdlib.

Reproduction

- Create a new Node.js package
- `pnpm add @stdlib/stdlib`
- `import * as s from "@stdlib/stdlib"`

Expected Results

Node should not throw the error when loading `@stdlib/stdlib`. I expect `lapack` should be included via the dependencies.

Actual Results

Error: Cannot find module '@stdlib/lapack'
Require stack:
- [root]/node_modules/.pnpm/@stdlib+stdlib@0.3.0/node_modules/@stdlib/stdlib/lib/main.js
- [root]/node_modules/.pnpm/@stdlib+stdlib@0.3.0/node_modules/@stdlib/stdlib/lib/index.js
 ❯ Object.<anonymous> ../../node_modules/.pnpm/@stdlib+stdlib@0.3.0/node_modules/@stdlib/stdlib/lib/main.js:190:32

Update: manually running pnpm add @stdlib/lapack allowed the test to execute successfully.

I saw in the README that LAPACK is intended to be an optional dependency for performance. At first glance it looks like the pure JS fallback isn't working correctly -- at least under my pnpm-based setup.

I'm happy to help diagnose this; just let me know what you need. The code that I'm running isn't publicly available but I could probably whip up a test jig if necessary.
