Publish JExtract-generated source code alongside compiled bindings

[Copilot]

JExtract generates Java source code for WebGPU bindings, but only the compiled JAR was being published. This prevents users from attaching sources in their IDEs and makes debugging harder.

Changes

lib/build.gradle:

• Added sourcesJar task to package generated code from build/bindings/
• Included sources JAR in Maven publication artifacts
• Updated bindings task to output both JARs

GitHub Actions workflow:

• Modified artifact upload to include webgpu-sources.jar alongside webgpu.jar

Result

Both GitHub Actions artifacts and Maven publications now include:

• webgpu.jar - compiled bindings
• webgpu-sources.jar - generated source code

Original prompt

publish the source code generate by the JExtract both in upload-action and publish-action

Inconsistent artifact specification in Maven publication. Line 102 uses file() while line 103 directly references the task. For consistency and to follow Gradle best practices, line 102 should directly reference the jar task instead of using file(\"build/webgpu.jar\"), as the build output path is already defined by the jar task configuration.

Suggested change

	artifact file("build/webgpu.jar")
	artifact jar

Hardcoded path instead of using Gradle's file references. Consider using from file('build/bindings') or better yet, referencing the location through a variable or property to make the configuration more explicit and maintainable.
