approved-tasks.json, dashboard/status.json, anaf-monitor/monitor.log are auto-modified by background processes (heartbeat, cron jobs, ANAF monitor). Untracking them stops the noisy "auto-commit from dashboard" churn. Files stay on disk; readers (router._load_approved_tasks etc.) already handle missing files by returning empty defaults.
