AxiomCorev1.0

This plugin adds idempotency support for a site's REST API, designed for developers building custom integrations or applications that interact with the API. It ensures that when a client retries a request due to a network error, the server processes it only once, preventing duplicate actions like double-charges or repeated content creation.

• Idempotency Key Support: Clients can include a unique key in the request header or body, which the server uses to identify and prevent duplicate processing of the same operation.
• Configurable Key Handling: The name of the idempotency key and the HTTP methods it applies to (like POST, PUT, PATCH) can be customized through the plugin's settings interface.
• Extensible Architecture: Core components like the DataStore, RequestHasher, and ResponseSerializer are built as interfaces, allowing developers to swap in custom implementations (e.g., using Redis for storage) via provided hooks and dependency injection.
• Request Polling for Concurrent Calls: If a request with an existing key is already being processed, the plugin polls for the result and returns it, preventing errors for simultaneous retries from the same client.
• Developer Tools: Includes a sample request interface for testing configuration and provides detailed actions and filters for advanced customization of the plugin's internal behavior.
