Add the Java binding over the C ABI hub (Panama/FFM) (#233)

Adds a Java binding (`bindings/java`) over the C ABI hub — the fourth language stecker after C#, Go and R, reaching the hub through the Java Foreign Function & Memory API (Panama, `java.lang.foreign`, final in Java 22) rather than JNI or jextract. ## What's here - **`bindings/java`** — a Maven module (`org.wickra:wickra`) exposing all 514 indicators as idiomatic `AutoCloseable` classes. The downcall handles (`internal/NativeMethods.java`), the per-indicator wrappers and the output records are generated from `bindings/c/include/wickra.h` (same eight-archetype taxonomy as the C#/Go/R generators: scalar/batch, multi-output, bars, profile, values-profile, array-input). The opaque handle is a `MemorySegment` freed by a registered `java.lang.ref.Cleaner` action; multi-output returns a `record` (`null` at warmup), bars a `record[]`, profiles a record with a trailing `double[]`. The hand-written `WickraNative` resolves the native library (a bundled per-platform copy, or a `target/release` fallback for local development) and validates it against a sentinel symbol. repr(C) struct offsets are computed in the generator so the FFM reads land on the exact bytes. - **`examples/java`** — the full example suite mirroring C/C#/Go/R: streaming, backtest, multi_timeframe, parallel_assets (parallel streams), three strategies, and `FetchBtcusdt`/`LiveBinance`. - **CI** — a `java` job builds the C ABI library, sets up JDK 22 (Temurin, with a CDN-flake retry), runs the archetype test suite and the seven offline examples on Linux, macOS and Windows. - **Release** — a gated `java-publish` job (skipped until the `JAVA_PUBLISH_ENABLED` repository variable is set) stages the native libraries from the `wickra-c-<triple>.tar.gz` assets into the binding's resources and deploys to Maven Central with GPG signing. Independent of the GitHub-release job, like the NuGet job. - **Docs** — Java added to the README languages table, project layout, building/testing and comparison table, CONTRIBUTING, ARCHITECTURE, the examples index, the issue/PR templates, the About-description template, and the other binding READMEs. ## Requirements Java 22+ (the FFM API is final since Java 22). The binding requires `--enable-native-access=ALL-UNNAMED` at runtime; the test and example runners pass it automatically. No Rust crate or `Cargo.toml` change — the Java binding is standalone and additive. The generated `*.java` are committed (like the node `index.js`/`index.d.ts`); the generator stays private.

+**Streaming-first technical indicators for the JVM, on the Java Foreign Function
+& Memory API — prebuilt native library, no JNI, no system dependencies.**
+
+Wickra is a multi-language technical-analysis library with a Rust core and
+bindings for Python, Node.js and WebAssembly, plus a C ABI for C/C++, C#, Go, Java, R
+and any other C-capable language. Every indicator is an O(1) streaming state
+machine, so live trading bots and historical backtests share the exact same
+implementation. This package is the Java binding; it consumes the C ABI hub
+through the Panama FFM API (`java.lang.foreign`) and exposes all 514
+streaming-first indicators as idiomatic `AutoCloseable` classes.
+
+## Requirements
+
+- **Java 22 or later** (the FFM API is final since Java 22; no preview flag).
+- The FFM API is *restricted*: pass `--enable-native-access=ALL-UNNAMED` when you
+  run your application to silence the native-access warning.
+
+## Install
+
+Maven:
+
+```xml
+<dependency>
+  <groupId>org.wickra</groupId>
+  <artifactId>wickra</artifactId>
+  <version>0.7.8</version>
+</dependency>
+```
+
+Gradle:
+
+```kotlin
+implementation("org.wickra:wickra:0.7.8")
+```
+
+The native library ships prebuilt per platform (Linux, macOS, Windows — x64 and
+arm64) inside the jar and is extracted automatically on first use. There is
+nothing to compile.
+
+## Quick start
+
+```java
+import org.wickra.Ema;
+import org.wickra.Rsi;
+
+// Batch: run an indicator over a whole series (NaN at warmup positions).
+double[] prices = new double[1000];
+for (int i = 0; i < prices.length; i++) {
+    prices[i] = 100.0 + i * 0.1;
+}
+try (Ema ema = new Ema(20)) {
+    double[] values = ema.batch(prices);
+}
+
+// Streaming: the same indicator, fed tick by tick in O(1).
+try (Rsi rsi = new Rsi(14)) {
+    for (double price : liveFeed) {
+        double value = rsi.update(price); // NaN during warmup, no recomputation
+        if (Double.isFinite(value) && value > 70) {
+            System.out.println("overbought");
+        }
+    }
+}
+```
+
+`batch(prices)` and feeding the same prices through `update()` produce identical
+values — the equivalence is enforced by the test suite. Multi-output indicators
+(MACD, Bollinger, ADX, …) return a `record`, `null` while warming up. Each
+indicator owns a native handle freed by a `Cleaner`; `close()` releases it
+eagerly (use try-with-resources).
+
+## Documentation
+
+The full indicator catalogue, guides, quickstarts, and API reference live in
+the main repository and documentation site:
+
+- **Repository & full indicator list:** <https://github.com/wickra-lib/wickra>
+- **Docs** (quickstarts, cookbook, TA-Lib migration): <https://docs.wickra.org>
+- **Runnable examples:** [`examples/java/`](https://github.com/wickra-lib/wickra/tree/main/examples/java)
+
+Wickra ships native bindings for Python, Node.js, WebAssembly and Rust, plus a
+C ABI hub that any C-capable language (C, C++, Go, C#, Java, R) links against —
+all exposing the same indicators from the shared, `unsafe`-forbidden Rust core.
+
+## Disclaimer
+
+Wickra is an indicator toolkit, not a trading system. The values it computes
+are deterministic transforms of the input data — they are not financial advice
+and do not predict the market. Any use in a live trading context is at your own
+risk. The library is provided **as is**, without warranty of any kind.
