The Node binding shipped only one example (a synthetic streaming demo),
while Python and Rust both have a CSV backtest. Add the Node counterpart of
examples/python/backtest.py and crates/wickra/examples/backtest.rs: it reads
an OHLCV CSV, streams every candle through a basket of indicators (SMA, EMA,
RSI, MACD, Bollinger Bands, ATR, ADX, OBV) via the O(1) update call, and
prints a per-series summary.
With no argument it runs against the bundled BTCUSDT daily dataset, so it is
runnable out of the box; pass a path to use any other OHLCV CSV.
