kingchenc 1295b63e1f Wire release pipeline to crates.io, PyPI, and npm
On every v* tag push the release workflow now publishes the project to
all three public registries in parallel:

- crates.io: wickra-core then wickra-data then wickra, with a 45-second
  sleep between each so the registry index can refresh before the next
  publish step asserts the previous version is available.

- PyPI: maturin-action builds wheels for Linux x86_64 + aarch64, macOS
  x86_64 + aarch64, and Windows x64, plus an sdist; all artefacts upload
  to PyPI via MATURIN_PYPI_TOKEN.

- npm: napi-rs builds a native binary per platform (linux-x64-gnu,
  darwin-x64, darwin-arm64, win32-x64-msvc), publishes each as its own
  platform package, then publishes the main `wickra` meta-package
  that resolves to the right platform at install time.

- WASM: wasm-pack builds the bundler-target package and publishes it as
  `wickra-wasm` on npm, with the auto-generated package.json enriched
  with the author/repo/license metadata.

Package metadata was unified so all targets point at kingchenc/wickra
on GitHub; the Node binding is now plain `wickra` (the @wickra/ scope
was unnecessary because the bare name was free). README install table
updated to match.

@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');
}
