feat: GF-T on-chip binary logistic classifier (proven on AX7203, 100% held-out)

[gHashTag]

New spec gft_logistic.t27 — on-chip SGD step of a binary classifier: logit z=w0x0+w1x1, p=hard_sigmoid(z)=clamp(0.5+0.25z,0,1), gradient dL/dz=p-y, update w_j-eta(p-y)*x_j; returns (w0'<<32)|w1'. Division-free hard-sigmoid (a runtime reciprocal maps to a $div/CARRY4 the open P&R flow cannot place). In-spec tests PASS. Proven on a live AX7203 (uart_logistic.v): streaming labeled 2D points for a hidden boundary (class1 iff x0+x1>0), the board learns on-chip and classifies 8/8 held-out correctly (100% generalization) — classification, not just regression. docs/NOW.md updated.
