## Summary Fixes intermittent failures in the `parallel dlx calls of the same package` test, especially on Windows CI. Multiple race conditions were discovered when concurrent `pnpm dlx` processes share the same Global Virtual Store (GVS): - **Content-verified skip in GVS mode**: When `safeToSkip` is true and a rename fails because the target already exists (ENOTEMPTY/EEXIST/EPERM), verify all files match (inode or content comparison) before skipping. Falls through to `renameOverwriteSync` if content doesn't match. - **Tolerate EPERM during bin creation on Windows**: `cmd-shim`'s `chmod` can fail with EPERM when another process holds the `.bin` file. Warn instead of crashing. - **Handle EPERM in DLX cache symlink**: Added EPERM to the list of tolerated errors when creating the DLX cache symlink, as Windows can throw this when another process has the symlink open. ## Test plan - [x] `parallel dlx calls of the same package` test passes on Windows CI - [x] Full test suite passes on both Ubuntu and Windows
