Phase 1: Foundation & Stability Infrastructure

✅ BullMQ job queue system installed and configured
✅ Zod validation schemas for all collections
✅ Spintax validator with integrity checks
✅ Work log helper for centralized logging
✅ Transaction wrapper for safe database operations
✅ Batch operation utilities with rate limiting
✅ Circuit breaker for WordPress/Directus resilience
✅ Dry-run mode for preview generation
✅ Version management system
✅ Environment configuration

This establishes the bulletproof infrastructure for Spark Alpha.
