Extended convergence test from 50 → 80 epochs to give C51 distributional
loss proper headroom after warmup transition at epoch 5.
80-epoch results (RTX 3050, hidden=[64,64]):
Best Sharpe: 9.08 at epoch 29
Final Sharpe: 4.09 at epoch 80
Grad norm: 0.696→0.716 (stable nonzero throughout)
Q-values: 0.18→0.78 (growing, stable)
Loss: 14.5→4.5 (converging)
MaxDD: 3-17% range
Trades: 42-74 per epoch
