Refactor Target to support multiple connection types (listener+conns map, packetConn, serialPort). Add acceptLoop, readLoopPacket, readLoopSerial. Mode-aware Broadcast dispatches to all accepted conns (TCP-S), known remotes (UDP-S), or serial port. Update flag help, command completions, and TUI panel hints.
