REAL TRADING EXECUTOR — Only loaded when PAPER_MODE=false.

DO NOT MODIFY unless explicitly asked and paper trading thresholds are met:
  - Sharpe Ratio > 0.5 (over 4+ weeks)
  - Win Rate > 52%
  - Calibration Score > 0.7
  - Explicit `make promote` confirmation

This file is intentionally minimal until paper trading validates the strategy.
