Split LXMF runtime ownership into focused peer, path, link, propagation, and delivery helpers while keeping the adapter as the coordination layer.
Make chat delivery refs and send-result events protocol-aware across Reticulum, Meshtastic, and MeshCore, including Sent/Delivered/Failed semantics, UI badges, retry lookup, and store persistence.
Fix Meshtastic MQTT private replies to publish encrypted direct packets and cover the new delivery behavior with smoke tests.
Carry conversation timestamps into the legacy pager list, force names/previews/time/unread labels to single-line bounded widths, keep MeshCore unknown senders from rendering as Me, show protocol prefixes in Contacts, and rebind the shared two-pane navigation after refresh so Team/Chat/Contacts filters become reachable.
