Build a Retry-Safe Strapi Webhook Receiver: Idempotency Keys, Backoff, and a Dead-Letter Queue

Strapi's webhooks are simple: an entry changes, Strapi fires a POST request at a URL you configured. What Strapi's docs don't tell you is what happens next — because "next" is entirely your problem. Strapi retries failed deliveries, which means your receiver can get the same event twice.
