fix: INPUT toggle no longer disrupts CLK timing in waveform

Browse Source 
recordSample() (triggered by user INPUT toggle) now only advances
timeStep when the simulation is stopped. When sim is running, it
records at the current timeStep without advancing it, so the clock's
regular tick cadence is never stolen by manual interactions.
