Function run_network_loop 

pub async fn run_network_loop(
    swarm: Swarm<BillPouchBehaviour>,
    cmd_rx: Receiver<NetworkCommand>,
    state: Arc<RwLock<NetworkState>>,
    listen_addr: Multiaddr,
    storage_managers: StorageManagerMap,
    outgoing_assignments: OutgoingAssignments,
    remote_fragment_index: Arc<RwLock<RemoteFragmentIndex>>,
) -> BpResult<()>

Drive the P2P event loop until shutdown.

Spawned as a background task by run_daemon. Runs a tokio::select! loop that concurrently:

• polls the libp2p swarm for events (gossip, mDNS, Identify, Kademlia),
• reads NetworkCommands from cmd_rx and mutates swarm state.

The loop exits when the command channel is closed or a Shutdown command is received.

Arguments

• swarm — the libp2p swarm built by build_swarm.
• cmd_rx — receiving end of the daemon → network command channel.
• state — shared NetworkState updated from gossip messages.
• listen_addr — multiaddr to bind the TCP listener on.
