- TCPClientInterface overrides needs_transport_headers() so hops==1 packets get HEADER_2 wrapping through the hub - Track savedCounter in LXMFMessage and use direct filename lookup for status updates, fixing LoRa uptime-timestamp precision loss that caused SENT status to revert to QUEUED on reload - Remove timestamp-based re-sort in loadConversation() which broke chronological order when mixing LoRa (uptime) and TCP (epoch) timestamps; counter-based filenames already provide correct order
