v0.4.0 - per-coordinate SNR gate redesign

Measured, 5 seeds:
  30% label noise: 0.810 vs AdamW 0.679 (+13.1 pts)
  15% label noise: 0.857 vs AdamW 0.763
  clean:           0.935 vs AdamW 0.931
  high LR:         38 steps vs Adam 70

Two EMAs per parameter -- identical optimizer memory to Adam.
No host sync in step(); AGAR scale-invariant; robustness decoupled from betas.
Benchmarks audited: 3 confounds removed, B5 data-source bug fixed, B1 multi-seed.

NOT YET VALIDATED ON A REAL DATASET -- see CLAUDE.md section 9.
