When no --remote is configured, the relay now operates in bridge mode: - First client connects → echoes while waiting for a peer - Second client connects → both clients are bridged bidirectionally - A's packets go to B, B's packets go to A - Stats logged every 5 seconds (a_to_b / b_to_a packet counts) - Falls back to echo if only one client connects This enables the core use case: two clients on different networks calling each other through a single relay.
