Subject: [PATCH 4/4] Fix Netlify CLI permissions issue on GitHub-hosted
 runners

Create ~/.config/netlify directory with proper permissions before running
Netlify CLI to prevent EACCES errors. This issue occurs because the CLI
is installed globally with sudo but runs as the regular user, requiring
write access to the config directory.
