Transmission Line (Bergeron half)

One island-local terminal of a split Bergeron transmission line. Not placed directly — the netlist converter emits a pair of these (roles a/b) for each travelling-wave line whose one-way travel time clears the time step, so the two circuits decouple into separate electrical islands and exchange delayed history through arena rings. The lumped PI / short-line fallback uses the two-port Transmission Line component instead.
