CronLint -- Scheduled Task & Cron Job Anti-Pattern Analyzer

CronLint scans codebases for scheduled task and cron job anti-patterns: overlapping execution risks, timezone scheduling errors, missing error recovery, resource contention, lifecycle management issues, and observability gaps. It uses regex-based pattern matching against 90 scheduling-specific patterns across 6 categories, lefthook for git hook integration, and produces markdown reports with actionable remediation guidance. 100% local. Zero telemetry.

Note: CronLint focuses on cron jobs, schedulers (node-cron, APScheduler, Quartz, Celery beat, Bull/BullMQ), setInterval/setTimeout scheduling, Kubernetes CronJobs, and periodic task code. It detects anti-patterns in scheduling logic, not HTTP cron endpoints.
