syncduke: design doc for Synchronet node status/listing integration

Design for porting SyncDOOM's in-game node features to SyncDuke: Ctrl-U who's- online banner, NODE_EXT status broadcast ("playing SyncDuke"), and a neutral incoming inter-node-message display. Paging (sending) deferred. Captures the architecture (new syncduke_node.c), banner rendering via the existing overlay/ signature/repaint machinery, and the key decisions (verbatim messages, exit clears only the NODE_EXT flag, door owns the clear).
