Description

During the composer update or composer install process, the post-autoload-dump event, which runs php artisan package:discover, fails on Windows environments. The failure occurs when the Filesystem attempts to rename a temporary cache file, but the file is locked by another process (likely an antivirus or file indexing service), causing a "permission denied" error.

This is a common race condition and file locking issue on Windows, particularly when the bootstrap/cache directory is being scanned by third-party software.

In Filesystem.php line 219:

rename(...\bootstrap\cache\pacDE7.tmp, ...\bootstrap\cache/packages.ph
  p): The process cannot access the the file because it is being used by another process (code: 32)

Steps To Reproduce

1. Set up a Laravel project on a Windows machine.
2. Run composer update or composer install.
3. The error has a high probability of occurring if a real-time antivirus scanner or Windows Search Indexer is active. The issue is intermittent.
