feat: TA-Lib candlestick patterns — matching-low/lines/three-methods (part 7 of 9) (#139)

Adds five TA-Lib candlestick patterns, all `Input = Candle`, `Output = f64`
(`+1.0` bullish / `-1.0` bearish / `0.0` no pattern), wired across core,
Python/Node/WASM bindings, fuzz, and tests.

- **Matching Low** (`CDLMATCHINGLOW`) — 2-bar bullish reversal: two black candles in a decline share the same close, signalling selling pressure is exhausting; bullish +1.
- **Long Line** (`CDLLONGLINE`) — a candle whose range beats a rolling average of recent ranges with a body-dominated range; bullish +1 (white) / bearish -1 (black).
- **Short Line** (`CDLSHORTLINE`) — a compact candle whose range falls below the rolling average with a body-dominated range; bullish +1 (white) / bearish -1 (black).
- **Rising Three Methods** (`CDLRISEFALL3METHODS`) — 5-bar bullish continuation: a long white candle, three small bars holding within its range, then a white breakout to new highs; bullish +1.
- **Falling Three Methods** (`CDLRISEFALL3METHODS`) — the bearish mirror: a long black candle, three small bars within its range, then a black breakdown to new lows; bearish -1.

Counter 274 → 279 (mod-count == lib counted block; FAMILIES total 269 → 274).

Stacked on #138 (part 6 of 9); base retargets to `main` as the chain merges.
