fix(env): use rename-before-copy for all Windows shims on refresh

On Windows, .exe files may be locked by antivirus, search indexer,
or still-running processes. The remove_file call fails with "Access
denied" (os error 5), preventing npm/npx/vpx shims from being
refreshed.

Apply the same rename-to-.old pattern used for vp.exe to all tool
shims during --refresh. Cleanup of .old files runs after all shims
are created.
