Cron Job

Scheduled task that runs on a cron schedule with no persistent process.

What this demonstrates

• The `schedule` field defines a cron expression
• `restart: no` means the process runs once and exits
• No `provides` — cron jobs aren't servers, they don't expose ports

When to use this: Periodic tasks like backups, cleanup scripts, report generation.
