paper v2.34.1: SB/CB training loss decrease values from 3-seed (were s42)

Same bug pattern as v2.33's nudging test: the §4 ¶4 training loss
decrease values for SB+pen (-0.458) and CB+pen (-0.122) were s42
single-seed numbers labeled as part of the "three seeds" framing.
DFA+pen (-0.095 ± 0.007) was actually 3-seed.

Re-aggregated from existing JSONs (no new compute):
  SB+pen: per-seed {0.457, 0.444, 0.439} → 0.447 ± 0.008 (was 0.458)
  CB+pen: per-seed {0.123, 0.118, 0.124} → 0.121 ± 0.003 (was 0.122)
  DFA+pen: per-seed {0.104, 0.088, 0.093} → 0.095 ± 0.007 ✓ (unchanged)

Changes:
- §4 ¶4 training-loss trajectory line now uses 3-seed mean ± std for
  all three methods
- Appendix L paragraph now lists per-seed decreases for all three
- New auditable file: results/training_loss_decrease_3seed.json

Ratios SB ≫ CB ≈ DFA unchanged. The "all three functional metrics
agree on the SB ≫ CB ≈ DFA ordering" claim is unchanged.

Page layout: §1-§7 still 9 pages, refs p10, total 19 pages. 0 overfull.
