Pull request overview

This PR updates the AutoNAT documentation to reflect the addition of AutoNAT v2 capabilities in go-libp2p. The update transforms previously planned features (referenced as a proposal) into actual documentation for the implemented AutoNAT v2 protocol, which enables per-address reachability detection rather than just node-level detection.

Key changes:

  • Restructures autonat.md to clearly distinguish between AutoNAT v1 (node-level reachability) and v2 (per-address reachability)
  • Adds practical Go code examples demonstrating how to query confirmed addresses and subscribe to reachability change events
  • Updates hole-punching.md to reference AutoNAT v2's ability to determine reachability for individual addresses
