kingchenc 21bbd521b3 F11: add SuperTrend, Chandelier Exit, Chande Kroll Stop and ATR Trailing Stop
- Rust core: super_trend.rs (SuperTrend — ATR-banded trailing stop with
  flip logic; SuperTrendOutput { value, direction }), chandelier_exit.rs
  (Chandelier Exit — ATR stop hung off the window's highest high / lowest
  low; ChandelierExitOutput { long_stop, short_stop }),
  chande_kroll_stop.rs (Chande Kroll Stop — a two-stage ATR stop;
  ChandeKrollStopOutput { stop_long, stop_short }), atr_trailing_stop.rs
  (ATR Trailing Stop — a single ratcheting close-based stop). Each with a
  full Indicator impl, runnable doctest and reference / property / warmup
  / reset / batch==streaming tests.
- Python: PySuperTrend / PyChandelierExit / PyChandeKrollStop /
  PyAtrTrailingStop PyO3 classes (struct outputs as tuples and (n, 2)
  arrays) + module registration + .pyi stubs.
- Node: explicit SuperTrendNode / ChandelierExitNode / ChandeKrollStopNode
  / AtrTrailingStopNode with SuperTrendValue / ChandelierExitValue /
  ChandeKrollStopValue objects; index.d.ts and index.js updated.
- WASM: WasmSuperTrend / WasmChandelierExit / WasmChandeKrollStop /
  WasmAtrTrailingStop.
- Wiki: Indicator-SuperTrend/ChandelierExit/ChandeKrollStop/
  AtrTrailingStop.md plus rows in the "Trailing stop" table of
  Indicators-Overview.md and entries in Home.md.
- Add clippy.toml with doc-valid-idents for the proper noun "LeBeau".

cargo fmt + clippy (core/wickra/data/wasm/node) clean; 427 core tests,
25 data tests and 61 doctests green.

@wickra/wickra

Node.js bindings for the Wickra streaming-first technical indicators library.

Install

Once published, install per platform via the precompiled native package:

npm install @wickra/wickra

Build from source

cd bindings/node
npm install
npm run build
npm test

The native module is built via napi-rs. The build script produces a wickra.<platform>-<arch>.node binary in the package root that index.js loads at runtime.

Usage

import { SMA, RSI, MACD, version } from '@wickra/wickra';

console.log('wickra', version());

// Batch:
const prices = Array.from({ length: 1000 }, (_, i) => 100 + Math.sin(i * 0.1) * 5);
const rsi = new RSI(14).batch(prices);

// Streaming:
const macd = new MACD(12, 26, 9);
for (const p of livePriceStream) {
  const v = macd.update(p);
  if (v && v.histogram > 0) console.log('bullish crossover candidate');
}
