Windows CI pnpm install fails frequently, and rerunning a single job does not resolve it

## Summary

The `Test npm packages (rspack-windows-2022-large)` CI job frequently fails during `pnpm install --frozen-lockfile` with `ERR_PNPM_EPERM` or `ERR_PNPM_ENOENT` while copying files from the pnpm store.

At least 19 matching failures have been identified. Rerunning only the failed Windows job often reproduces the failure, while rerunning the entire workflow is more likely to resolve it.

Start with the GitHub Actions workflow for the `Test npm packages (rspack-windows-2022-large)` job and inspect the linked failed-run logs, focusing on the `pnpm install --frozen-lockfile` step. Compare failures from single-job reruns with full-workflow reruns; done means the Windows install no longer fails frequently or the workflow has a verified mitigation.
