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).
