[bug\_fix] pnpm: EPERM operation not permitted, rename ... \(hardlink issues\)

Disable hardlinks in pnpm by setting package-import-method=clone or copy in .npmrc, or run the terminal as Administrator on Windows, or ensure the pnpm store is on the same drive as the project.

Journey Context:
You convinced your team to switch from npm to pnpm for faster installs and disk space savings. On Windows, developers start getting random EPERM errors during pnpm install, mentioning rename or link operations failing. Deleting node\_modules helps temporarily but it returns. Some developers find it works when running PowerShell as Administrator, but that's not a viable workflow. You investigate and realize pnpm uses hardlinks by default to deduplicate packages from its content-addressable store. On Windows, creating hardlinks requires specific permissions or fails when the store and project are on different drives \(common with D: drives for repos\). You add package-import-method=clone to the .npmrc. This uses cloning \(reflinks on supported FS, fallback to copy\) instead of hardlinks. The permission errors disappear entirely, with only a minor speed tradeoff.
