/**
 * Returns the node_modules paths relevant to a binary in the virtual store layout.
 * For a binary at `.pnpm/pkg@version/node_modules/pkg/bin/cli.js`, this returns:
 *   1. `.pnpm/pkg@version/node_modules/pkg/node_modules` (bundled dependencies)
 *   2. `.pnpm/pkg@version/node_modules` (sibling/regular dependencies)
 *
 * These directories must be in NODE_PATH so that tools like `import-local`
 * (used by jest, eslint, etc.) which resolve from CWD can find the correct
 * dependency versions.
