Me Here af8e7e236b PM_K-1 hardware: render simulations as PNG plots (gnuplot) so they're viewable ...

Added gnuplot to the EDA container; sims now wrdata their curves and plots.gp renders 5
PNGs in hardware/eda/sim/plots/ (open in any browser/viewer):
- input_loading: instrument(1M) preserves the +16dB pickup resonance the line(25k) flattens
- stage1_cmrr: common-mode leakage, 0.1% vs 1% resistor mismatch
- stage2_recon: DAC reconstruction filter (flat to 20k, -3dB ~75k)
- stage4_driver: balanced differential response (flat across audio)
- stage1_phantom: +48V transient clamped at the op-amp input, decays to ~0
(.data intermediates git-ignored.)
