Deploy Hurst/VPIN directional strategy to live + paper

Live node: - Added Hurst VPIN to STRATEGIES (BTC, 0.00024 size, 00) - Feed BTC price into dollar-bar Hurst/VPIN every 5 ticks - Signal: BUY/SELL when H>0.55 + VPIN>0.25 + direction bias Paper trader: - Added Kalman Pairs, Avellaneda-Stoikov, Hurst VPIN strategies - All 00 allocation, matching live node asset distribution - Hurst/VPIN signal from BTC mid-price dollar bars Strategy file: hurst_vpin_live.py (lightweight price-tick mode)
