feat: GF-T 3-class linear classifier inference (proven on AX7203, 16/16)

[gHashTag]

New spec gft_classify3.t27 — 3-class linear classifier inference: class = argmax_c(w_c0x0+w_c1x1). Reuses smul/sadd for logits and category/gt from the argmax stack. In-spec tests (c0/c1/c2) PASS. Proven on a live AX7203 (uart_classify3.v): a multiclass perceptron trained on host (99% train acc), 6 weights baked in; the board classifies 16/16 held-out across all 3 classes (100%). docs/NOW.md updated.
