drop card state that the buffer rules make impossible

CycleInfo's handledInputs/handledOutputs were left over from the design where
the Smelter and Reprocessing Plant had an implicit recipe and so had nothing to
name between cycles. Auto-recipe buildings carry a selected recipe now, and no
subclass has populated either field since.

The output chip's cap-less branch goes with them. It stood for an item left
over from a previous recipe, but selecting a recipe clears the buffers and
sizes them for that recipe alone, and the Salvage Bay's one buffer is sized by
config -- so every chip stands for a sized buffer and the bare count was
unreachable.
