Currently, the p2p server has a TODO comment in server.go:

TODO: track in-progress inbound node IDs (pre-Peer) to avoid dialing them.

This issue addresses a race condition where:

1. Node A initiates an inbound connection to us (starts handshaking)
2. Simultaneously, our dial scheduler attempts to dial Node A outbound
3. Both connections can proceed, resulting in duplicate connections to the same peer

This wastes resources and can cause issues with peer counting and connection management.
