ci: fix pnpm 11 not work

+/**
+ * Invoke the pkg packager (cross-platform, independent of node_modules layout).
+ *
+ * Background: on Windows, pnpm links node_modules/pkg to
+ * node_modules/.pnpm/pkg@<ver>/node_modules/pkg via a junction. Some CI
+ * environments (pnpm 11 + Windows runner) may fail to create that link,
+ * so executing node_modules/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.
