Peer Disconnects
A Pinecone node must immediately remove any state related to a peer that disconnects, including the last received root announcement from that peer.
If the chosen parent is the disconnected peer, the node must re-run the parent selection algorithm immediately, either selecting a new parent (with the equivalent Root public key and Root sequence) or by becoming a root node and waiting for a stronger update from a peer.
If the disconnected peer appears in any entry in the routing table, as either the Source port or Destination port, the entry should be removed from the routing table.
If the disconnected port is the Source port of the descending node entry, the descending entry should be cleared.
