Fix .gitignore to allow .npy in gradient_maps/ and upload all gradient numpy arrays

Upload v3 gradient saliency plots (corrected desync + pre-sigmoid logit gradients)

Upload v3 gradient maps (corrected desync + pre-sigmoid logit gradients for LMIC-TSBN)

Add raw gradient saliency maps v3 (pre-softmax logit gradients, 1000 traces, corrected desync)

Add gradient saliency line/area plots (50 files): per-model overlays, arch comparison, desync progression

Add all gradient saliency heatmaps (65 files): arch comparison, per-model, desync progression, thesis summary
