Add the Williams %R strategy

New williams_r indicator (in [-100, 0]) exposed as ctx.williams_r(period), and a
long-only mean-reversion strategy: enter when %R is at/below the oversold level,
exit when it reaches the overbought level, with an optional ATR stop. 11
strategies total. Adds indicator and strategy tests; smoke-tested on live
BTC/USDT 5m (backtest + parameter sweep).
