Conversation
Package specifiers always use `/`, so concatenating a scoped name or an `exports` target into a path yields `…\node_modules\@scope/pkg` on Windows. Comparisons against a sep-joined prefix — `inPath()` while walking symlinks — then fail, and the `node_modules` symlink of a scoped package is never emitted, leaving a standalone deployment without it. Only CommonJS was unaffected, because `resolveDir()` happens to pass its paths through `resolve()`; the ESM branch of `validateAndResolvePaths()` keeps them verbatim. Translate separators where a specifier becomes a path instead. Signed-off-by: Oldřich Jedlička <oldium.pro@gmail.com>
