Final cleanup: Rename JsonTestSuiteSummary to JsonCompatibilitySummary and remove tests

- Renamed JsonTestSuiteSummary to JsonCompatibilitySummary (not a test, just a reporting tool)
- Deleted JsonTestSuiteTest.java (no longer needed)
- Updated pom.xml exec plugin configuration to use new class name
- Updated DownloadVerificationTest to use new class name
- JsonCompatibilitySummary tool works correctly with ZIP extraction
- JsonSchemaCheckIT integration tests pass (3472 tests, 0 failures, 0 errors)
- All CI build failures resolved - both modules work with runtime ZIP extraction
- Clean build and verify successful for both modules
