Bash script to automatically install Supervisor (if not installed), create a Supervisor configuration to run Laravel's queue worker (php artisan queue:work) as the www-data user, and ensure it processes jobs one at a time (no parallel workers). Useful for setting up background job processing in Laravel using the database queue driver.
