Java plugin should not copy all jar files
Metadata
Current evaluation
Open design issue: Java plugins still hardlink every built JAR except those under .parts, allowing test artifacts into images; maintainers favor build-system-specific opt-in behavior.
Suggested action: keep open
Reason: JavaPlugin._get_jar_link_commands() still finds every *.jar under CRAFT_PART_BUILD except jars under .parts, confirming the problem remains. Maintainers acknowledged an opt-in approach and a possible 26.04 breaking change, but the reporter noted Maven and Gradle require build-system-specific resolution; stage/dist is only a documented workaround.

Issue body
### What needs to get done
Java plugin copies all jar files found in the build output. This includes test dependencies which should not be present in the resulting image.
Java plugin is unable to distinguish between test and runtime dependencies as it is build-system specific.
We need to design a way to determine the test dependencies,.
### Why it needs to get done
By default Java plugin deploys all the jar files including test dependencies.
