Webhook

Mammoth is intentionally boring infrastructure. It uses YAML configuration, JSON Schema validation, SQLite-backed operational memory, retries, checkpoints, and dead letters so operators can inspect and recover delivery state.

• SQLite dead-letter storage

• Helm-based Kubernetes deployment

Non-goals for 0.1.x
