This release carries the full post-audit work — 46 new indicators
(25 → 71), an eight-family taxonomy restructure, new bindings for
RollingVWAP, the WASM streaming-update parity, the pyo3/numpy CVE
fix, the SMA/Bollinger drift bound, the O(1) LinearRegression
refactor, the UlcerIndex deque and the PSAR is_ready/reset fixes
plus a refreshed example suite and wiki. The earlier 0.1.5 number
was never published; jumping straight to 0.2.0 is the cleaner signal
for the scope of the change.
Bumped:
- Cargo.toml workspace + wickra-core workspace-dep version
- bindings/python/pyproject.toml
- bindings/node/package.json + optionalDependencies (six platform pins)
- 6 x bindings/node/npm/<target>/package.json
- Cargo.lock regenerated
- CHANGELOG.md [0.2.0] header + compare-link
- docs/wiki/Home.md published-versions table
- docs/wiki/Quickstart-{Rust,Node,WASM}.md + Warmup-Periods.md
version-pinned narrative lines

- import wickra reports 0.2.0 with 72 indicator classes
The Quickstart-WASM page only mentioned `MACD` and `BollingerBands` as
multi-output indicators. After R3 (this branch) every candle-input
WASM class also exposes a structured `update`: `Stochastic`, `ADX`,
`Keltner`, `Donchian`, `Aroon` (plus `SuperTrend`, which has always
been there).
The "Multi-output indicators" section now lists every multi-output
shape in a table, and a short note at the end calls out the 0.1.5
parity: every candle-input indicator ships `update` / `batch` /
`reset` / `isReady` / `warmupPeriod`, so browser code doesn't need
to replay `batch` on each tick anymore.
Finish the per-language `examples/<lang>/` restructure by relocating the
WASM browser demo from bindings/wasm/examples/ to examples/wasm/.
* `examples/wasm/index.html` is the moved file; its WASM module import
becomes `../../bindings/wasm/pkg/wickra_wasm.js` so the demo still loads
the wasm-pack output without copying it.
* bindings/wasm/README.md, Quickstart-WASM.md, examples/README.md and the
root README "Languages" + project-layout block all point at the new
path. The serve command in the docs now says "serve the repository root
and open examples/wasm/index.html".
`bindings/wasm/examples/` is empty after the move; the now-empty
directory is removed.
The wiki had quickstarts for Python, Rust, and Node but none for the
WebAssembly binding, and the wickra-data crate (CSV reader, tick
aggregator, resampler, Binance feed) was not documented anywhere.
- Quickstart-WASM.md: install via npm, building with wasm-pack, and
streaming/batch/multi-output usage in a browser or bundler.
- Data-Layer.md: the wickra-data crate — CandleReader, TickAggregator
(including the opt-in gap fill), Resampler/resample_all, and the
feature-gated Binance live feed.
- Home.md links both from the wiki contents list.
