test(ci): gate that the generated trainer LEARNS -- XOR 4/4 + nonlinear held-out >=90%, incl. deep 3-layer (Refs #1764)

[gHashTag]

The bit-exact gates prove the generated RTL equals the model, but nothing CI-enforced that the algorithm actually learns non-trivial tasks. The generator's self-tests already assert exactly that — but they only ran when the file was executed by hand.

Adds python3 tools/gft_backprop_microcode.py as a CI step in emit-bitexact-gate.yml, enforcing per pull request:

• XOR trained 4/4 by the generated microcode;
• (2,4,1) on a noisy nonlinear dataset, held-out 58/60;
• (2,4,2) multi-output one-hot classifier, held-out 56/60;
• deep [2,4,3,1] (3-layer, 2 hidden) nonlinear task, held-out 59/60 — all ≥ 90%.

This strengthens the project's thesis: the method learns and scales beyond XOR (multi-layer, held-out generalization) in the model — the only limit was the open silicon flow's placement marginality, now addressed by the Vivado closure kit, not the algorithm.

CI-config only; no code change. Refs #1764
