iroh QUIC datagrams for peer-to-peer networking with NAT traversal,
donglora-client for radio access (direct USB or mux), ratatui TUI
with four-panel dashboard (peers, radio config, stats, packet log).
- Packet envelope with origin tracking, sequence numbers, RSSI/SNR
- Dual dedup: iroh-level (origin+seq) and radio echo (blake3 hash)
- SNR filtering per PROTOCOL.md (forward GOOD+MARGINAL, drop rest)
- Auto-generate config + identity on first run
- Graceful mux config fallback (adopts locked config if SetConfig rejected)
- WouldBlock workaround for donglora-client socket timeout bug
- Reconnect with exponential backoff on dongle disconnect
- CLI: show-id, generate-config subcommands, --log-only headless mode
