/**
 * Invoke the pkg packager (cross-platform, independent of node_modules layout).
 *
 * Background: on Windows, pnpm links node_modules/@yao-pkg/pkg to
 * node_modules/.pnpm/@yao-pkg+pkg@<ver>/node_modules/@yao-pkg/pkg via a junction.
 * Some CI environments (pnpm 11 + Windows runner) may fail to create that link,
 * so executing node_modules/@yao-pkg/pkg/lib-es5/bin.js directly throws
 * MODULE_NOT_FOUND.
 *
 * This script first resolves pkg via require.resolve and falls back to
 * scanning the .pnpm physical directory, so pkg is found whether the
 * junction exists or not.
