kingchenc e452d35a27 F13a: add Accelerator Oscillator, Balance of Power, Choppiness Index and Vertical Horizontal Filter

First half of the eight indicators that fill out the new family taxonomy.

- Rust core: accelerator_oscillator.rs (AcceleratorOscillator — AO minus a
  short SMA of itself), balance_of_power.rs (BalanceOfPower — per-bar
  (close-open)/(high-low)), choppiness_index.rs (ChoppinessIndex — summed
  true range over the high-low span, log-scaled) and
  vertical_horizontal_filter.rs (VerticalHorizontalFilter — net move over
  total move). Each with a full Indicator impl, runnable doctest and
  reference / property / warmup / reset / batch==streaming tests.
- Python / Node / WASM: classes wired through all three bindings
  (BalanceOfPower carries an explicit open column; VHF rides the scalar
  macros) plus .pyi stubs and __init__.py / __all__ entries.
- Wiki: four new Indicator-*.md pages.

The eight-family taxonomy restructure (Overview / Home / README / folder
layout) lands in F13c once F13b's four indicators are in.

cargo fmt + clippy (core/wickra/data/wasm/node) clean; 481 core tests,
25 data tests and 70 doctests green.

wickra-wasm

WebAssembly bindings for the Wickra streaming-first technical indicators library.

Build

You need wasm-pack and the wasm32-unknown-unknown Rust target:

rustup target add wasm32-unknown-unknown
cargo install wasm-pack

Then from the repository root:

wasm-pack build bindings/wasm --target web --release --features panic-hook

The compiled package lands in bindings/wasm/pkg/. Targets:

--target web for native ES modules in browsers
--target bundler for webpack/Vite/Rollup
--target nodejs for Node.js

Example

import init, { SMA, RSI, MACD, version } from "./pkg/wickra_wasm.js";

await init();
console.log("wickra:", version());

// Streaming
const rsi = new RSI(14);
for (const price of livePrices) {
  const v = rsi.update(price);
  if (v !== undefined && v > 70) console.log("overbought");
}

// Batch (returns a Float64Array; NaN for warmup positions)
const sma = new SMA(20).batch(new Float64Array(historicalPrices));

An interactive demo lives in bindings/wasm/examples/index.html. After building the package serve the bindings/wasm/ directory and open examples/index.html.
