It aims to provide a minimal, practical DTN node capable of: - Bundle transmission over TCP (CLA) - CBOR-encoded bundles - ACK-based delivery confirmation - Expiration and cleanup of bundles - CLI-based control and debugging

The goal is to extend this foundation to support BLE, LoRa, and dynamic routing for environments with intermittent connectivity—such as space, remote areas, or disaster recovery scenarios.
