exp13_v2_launcher.py — Run exp13 multiscale sweep with convnext_model_v2.json (ep=13).

Changes vs default exp13:
  - MODEL_1M  → convnext_model_v2.json  (calibration-fixed, always-positive z[13])
  - PROXY_B_DIM → 13  (z[13] is proxy_B dim in v2, vs z[10] in ep=17)

Everything else identical to exp13_multiscale_sweep.py.
Results logged to ../../exp13_v2_screening_run.log

Usage (from nautilus_dolphin/ dir):
  python dvae/exp13_v2_launcher.py --subset 14 --top_k 20   # Phase 1 screening
  python dvae/exp13_v2_launcher.py --subset 0  --top_k 0    # Full 56-day run

Why v2 should be better:
  ep=17 z[10]: ALWAYS NEGATIVE [-1.24, -0.30] → direct scaling configs hurt
  v2   z[13]: ALWAYS POSITIVE [+0.17, +1.46] → direct scaling configs work correctly
  Separation (proxy_B quartiles): 0.46 (ep=17) → 0.61 (v2) — 32% improvement
