docs(plugin): correct runtime smoke gate count 17 → 20 (ruvnet#1990)

The README still referenced "17 documented entry points end-to-end"
but ruvnet#1988 extended the smoke to 20 (pairs/adaptive/multi-indicator
gates added). Update the text to match the actual gate count and
list what's covered.

-> The 2.8.x line additionally adds a flag-style CLI dispatcher (`--backtest`, `--signal scan`, `--risk assess`, `--portfolio optimize`, `--regime`, `--train`, `--predict`, `--strategy-create`) running real math (SMA crossover / RSI mean-reversion / pairs z-score / adaptive regime-switching / multi-indicator RSI+MACD+Bollinger) against real Yahoo Finance data via `--live`. Supports `--walk-forward`, `--monte-carlo`, `--symbols A,B,C`, `--benchmark SPY`, `--optimize --param "name:min:max:step"`.
