Server (gatunad): - New --verbose/-v flag: logs lifecycle events at info level (DISCOVER, MANIFEST sent, OPEN, session established, CLOSE, OPEN_NAK). Without the flag, errors only as before. Client (gatuna): - OPEN_NAK and session CLOSE now send TCP RST to the local app instead of a graceful FIN. LingerOption(true, 0) causes Winsock to emit RST on close. The local app (e.g. ssh) sees a broken connection instead of a clean close, which is more honest about what happened (upstream was unreachable).
