feat: implement event notification system

- Add core event notification interfaces
- Support multiple notification backends:
  - Webhook (default)
  - Kafka
  - MQTT
  - HTTP Producer
- Implement configurable event filtering
- Add async event dispatching with backpressure handling
- Provide serialization/deserialization for event payloads

This module enables system events to be published to various endpoints
with consistent delivery guarantees and failure handling.
