Extract newRecorderObject, selectTarget, sniffingDial, buildSniffer, handleSniffedProtocol, and handleRawForwarding from Handle (200→87 lines). Move nil Router guard before sniffing for early failure. Log previously silent sniff and pipe errors at Debug level. Apply readTimeout to Pipe. Append :0 when target addr lacks a port. Reorder metadata fields and add doc comments on all exported symbols.
