Cloudflare Workers Observability

Handles the full observability stack for Cloudflare Workers: structured JSON logging with automatic PII redaction, Analytics Engine for custom metrics, and Tail Workers for real-time log aggregation. You get working patterns for request tracing with UUIDs, sampling high-volume logs to avoid cost explosions, and pushing errors to external services. The structured logging class is solid, includes actual redaction logic for tokens and passwords. Most useful when you're moving Workers to production and realize console.log isn't going to cut it anymore. The error prevention table is honest about real issues like log truncation at 128KB and missing Analytics Engine bindings.
