flowshield: TypeScript Resilience Library (Circuit Breaker, Retry, Timeout) for Edge Runtimes

Why Resilience Matters in Production Every distributed system fails eventually. APIs time out, databases get overloaded, third-party services go down. Without resilience patterns, one failing dependency can cascade into a full system outage. flowshield is a zero-dependency TypeScript-first resilience library that gives you composable fault-tolerance policies for any async operation.
