• update formatter and integration tests plus README documentation

Validation

• mvn -B -ntp -P!quality-gates-all -pl core '-Dtest=MainTest,ReportFormatterTest' test
• mvn -B -ntp -P!quality-gates-all verify

Closes #197

Pull request overview

This PR updates the JUnit XML “sidecar” output to surface CRAP/complexity/coverage details in GitLab-visible JUnit fields (notably the testcase name and testcase-level system-out), while preserving the existing JUnit properties and existing failure/skipped body text behavior. This aligns the tool’s output with GitLab’s Tests tab parsing limitations described in issue #197.

Changes:

• Extend JUnit testcase name to include a concise metrics summary (CRAP, CC, Cov + kind).
• Add testcase-level <system-out> diagnostics containing the same detailed diagnostic text already used for failure/skipped bodies.
• Update unit/integration tests and README documentation to reflect the new JUnit XML shape.
