feat: add Candlestick Patterns deepening (B14, 6 indicators) (#209)
B14 of the family-deepening roadmap — six candlestick patterns (479 -> 485), all in the **Candlestick Patterns** family.
**Fixed-lookback (candle-pattern macro bindings, neutral 0.0 during warmup):**
- **Tristar** — three-doji star reversal.
- **Harami Cross** — Harami whose second candle is a contained doji.
- **Tower Top/Bottom** — tall bar, small pause, tall opposite bar.
**Windowed / parameterized (hand-bound, `candle -> f64`):**
- **Frying Pan Bottom** — rounded U-shaped accumulation base, recovery-confirmed.
- **Dumpling Top** — rounded dome-shaped distribution top, breakdown-confirmed.
- **New Price Lines** — run of N consecutive new closing highs (+1) / lows (-1).
Window/Gap (Rising-Falling) dropped (SKIP — existing gap coverage). Wiring complete across core, Python, Node, WASM, fuzz, tests, README + docs counter (485) and CHANGELOG. Verified: core 3966 + doc 435, clippy clean, node 560, python 922.
