CI: Narrow Java test triggers

[vyasr]

Description

Replace the broad test_java changed-files blacklist with a positive set of inputs shared by the cuDF Java and cuDF Spark JNI compatibility jobs.

The Spark JNI job consumes cuDF Java native sources, so Java changes intentionally run both jobs.

📝 Summary

Summary by CodeRabbit

• Tests
  • Refined automated validation to run only the relevant C++, CMake, linting, and Java checks for each type of source change.
  • Java and cuDF Spark JNI validation now also runs when shared C++ code changes.
  • Unrelated file changes no longer trigger these test workflows.

Walkthrough

The workflow replaces broad Java path matching with explicit paths. Java build and cuDF Spark JNI jobs also trigger when shared C++ files change.

Changes

Java workflow path matching

Layer / File(s)	Summary
Explicit Java test paths .github/workflows/pr.yaml	The test_java group uses explicit Java, shared C++, build, script, and workflow paths. The Java build and cuDF Spark JNI jobs also respond to cpp_files changes.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 38a31

The new positive path matching can skip Java compatibility testing for VERSION-only changes that affect native build versioning. Add VERSION to the applicable trigger group before merging so those changes continue to run both Java jobs.

Add VERSION to cpp_files.

cpp/CMakeLists.txt includes cmake/rapids_config.cmake, which reads the root VERSION file. A VERSION-only change can skip both Java jobs because it matches none of their path groups.
