🧩 Feature: Integrate libp2p into go-perun

Objective

Integrate libp2p as a transport layer in go-perun to enable modular, peer-to-peer communication, replacing or augmenting the existing communication backend.

Motivation

• Standardize transport using a widely adopted p2p framework
• Benefit from libp2p’s NAT traversal, multiplexing, encryption, and peer discovery
• Facilitate interoperability with other libp2p-based systems

Location: wire/net/libp2p

Tasks

• Migrate perun-libp2p-wire implementation to go-perun.
• Integrate with go-perun wire protocol and peer address resolution
• Add tests for transport integration (unit + integration)
• Update documentation and examples to support libp2p usage

Notes

This integration should be designed in a modular way to preserve backward compatibility and allow future transport backends.
