prepareDecompiledSourcesForIde
Decompiles the server jar and all dependencies declared in vineImplementation, vineCompileOnly, or vineDecompileTargets into build/generated-sources-m2 and build/generated-sources-ivy.
This is useful for IDE source attachment. For the Hytale server jar, the plugin also injects hosted Hytale Server API Javadocs into the generated Vineflower sources by default, so documentation can appear directly in IDE source views instead of only through external Javadoc lookup.
