Upgrade to full native Deep-UFM semantic-v4 reproduction

claims 5-6: measured Hessian outlier dynamics and alignment (linear) + ReLU comparison

claims 1-4: train the deep linear UFM and report measured Hessian rank/spectrum, Papyan decomposition, gradient coefficients and weight Gram

Replace the source-reported claim-5 page with an independent UFM training run and exact Hessian spectrum

Remove duplicate claim-5 page (merged into the canonical one)

Claim 5: train the deep linear UFM and compute the exact Hessian spectrum (was source-reported); outlier count equals K^2 at K=2,3,4 across depths 2-3

Emergency repurpose: validated low-dimensional-spectra reproduction
