kingchenc a5fe2e71c4 release: bump 0.9.2 -> 0.9.3 (#325 )

Release the native data-layer bundle.

`0.9.3` ships everything merged since `0.9.2`:

- **Data layer in all 10 languages** — `CandleReader` (CSV), `TickAggregator`, `Resampler`, live `BinanceFeed` (WebSocket) and the historical `fetch_binance_klines` (REST), each cross-language golden-pinned.
- **`name()` on every indicator** in all 10 languages (514 indicators, golden-pinned).
- **Python is now zero third-party deps** — NumPy is optional (`pip install wickra[numpy]`); `batch` returns a stdlib `array.array` / buffer-protocol `Matrix` (breaking; results numerically identical, batch throughput tradeoff noted in the CHANGELOG).
- **Binance feed: missing `3d` / `1M` intervals** fixed.

Pure version-string bump on top — `bump_version.py` touched 19 files (Cargo + Lock, pyproject, all node package.json/locks + 6 platform stubs, pom + csproj + DESCRIPTION, SECURITY, CHANGELOG `[0.9.3]` + compare URLs). `cargo fmt`/`clippy -D warnings`/`test --workspace --all-features` all green locally (4225+ tests, 0 failed).

The tag/publish is **not** part of this PR — it waits for explicit GO (irreversible publish to crates.io / PyPI / npm / NuGet / Maven / Go / r-universe).

Wickra examples — Java

Runnable examples for the Wickra Java binding. Each example is a small main class that uses the org.wickra:wickra artifact and resolves the native library automatically (from target/release during local development, or the bundled per-platform library when packaged).

Build the native library and install the binding to your local Maven repo first, then run any example with the exec plugin:

cargo build -p wickra-c --release
mvn -f bindings/java install -DskipTests
mvn -f examples/java compile
mvn -f examples/java exec:exec -Dexec.mainClass=org.wickra.examples.Streaming

(The exec:exec goal forks a JVM with --enable-native-access=ALL-UNNAMED, the flag the FFM API needs.)

Example	What it does	Main class
`streaming`	Feed a synthetic price series through SMA / EMA / RSI / MACD tick by tick.	`org.wickra.examples.Streaming`
`backtest`	Compute a basket of indicators over an OHLCV series and print a summary.	`org.wickra.examples.Backtest`
`multi_timeframe`	Resample a 1-minute series into 5m / 15m and print an indicator per timeframe.	`org.wickra.examples.MultiTimeframe`
`parallel_assets`	SMA(20) batch over a panel of assets, serial vs parallel streams, with speedup.	`org.wickra.examples.ParallelAssets`
`strategy_rsi_mean_reversion`	RSI(14) mean-reversion with a PnL / Sharpe / max-DD summary.	`org.wickra.examples.StrategyRsiMeanReversion`
`strategy_macd_adx`	MACD crossover entries gated by ADX(14) > 20.	`org.wickra.examples.StrategyMacdAdx`
`strategy_bollinger_squeeze`	Bollinger-squeeze breakout with an ATR(14) trailing stop.	`org.wickra.examples.StrategyBollingerSqueeze`
`fetch_btcusdt`	Download real BTCUSDT klines from the Binance REST API into a CSV.	`org.wickra.examples.FetchBtcusdt`
`live_binance`	Stream live Binance klines through EMA(20) over a WebSocket.	`org.wickra.examples.LiveBinance`

fetch_btcusdt and live_binance require network access; the rest run offline on deterministic synthetic data. Shared helpers (synthetic data, CSV loader, equity summary) live in MarketData and Equity.
