Radio reconnection: - Add connect_mux_auto() to donglora-client — mux-only connect that never silently falls back to USB serial (matches Python client's sticky mux) - Fix codec.rs read_frame() to handle WouldBlock alongside TimedOut - Add liveness ping (2s) to detect dead mux connections - Treat transmit errors as fatal (trigger reconnect) - Faster backoff: 250ms initial, 5s max, resets after stable connection TUI improvements: - Redesign packet log: RF+Net columns show full packet path (RX→TX), hash column with dedup ellipsis, fixed-width columns throughout - Move activity charts to right column (fills remaining width) - 1-second sparkline buckets instead of 10-second - Radio panel shows "(disconnected)" with red border when mux is down - Header: status pills left, clock with TZ right-justified, Ctrl-C quits - Local time via jiff crate with proper timezone abbreviation DHT strategy: - Alone: read every 3s, merge-publish every 30s (preserves existing peers) - Connected: publish authoritative [self + neighbors], purging stale peers - Publish immediately on first neighbor join Signal handling: - SIGINT and SIGTERM both trigger graceful shutdown via cancellation token - All paths go through swarm.shutdown() to update DHT before exit
