I Luk Kim bb659cf7ae Add reaction-based position sizing to reduce mean-reversion loss risk
New feature: reaction_size_cap_threshold in RiskConfig
- When abs(reaction_day_return) > threshold, position size scales down
- Formula: scaler = threshold / abs(reaction) (linear inverse)
- E.g. threshold=8%: 8% reaction → 100%, 16% → 50%, 24% → 33%

Paper trading impact simulation (top 10 trades):
- PII (react +14%): loss $501 → $288 (saved $214)
- VSCO (react +18%): loss $792 → $350 (saved $442)
- RYTM (react +12%): loss $397 → $256 (saved $141)
- Winners (react <5%): unchanged (SSRM, FLS, LW, KGS all 100%)
- Total loss reduction: $2,610 → $1,813 (-30%)
- Net PnL improvement: +$797

v6new.24 backtest: Train SQS 92.5 (session best), risk=75.6.
Public SQS 52.5 (lower return due to sizing, but best risk profile).
