Feature 08: Centralized Log Forwarding MVP
==========================================

The MVP introduces asynchronous forwarding, retry behavior, and monitor endpoints.

Core Capabilities
-----------------

- Async log forwarding pipeline.
- HTTP sink implementation.
- Buffering and retry-oriented behavior.
- Local monitor endpoints for health and metrics.
- Metrics in JSON and Prometheus text formats.
