Remove backtest.py, backtest_gpu.py, metrics.py, local CSV data, Dukascopy loader, and all backtest CLI modes from main.py. Rebalance engine weights: leading indicators (divergence, RSI, stochastic, BB) now carry 66% of signal weight vs 34% for lagging (EMA, MACD). Add ws_twelvedata.py for live tick streaming. Drop pyarrow and tqdm deps. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
