Use Python to generate surefire test summary

Replace the test-summary/action step with an inline Bash step that runs a Python script to parse Surefire XML reports (target/surefire-reports/TEST-*.xml). The script aggregates totals (passed, failed, errors, skipped, total), lists up to 20 failed test cases, and appends a Markdown-formatted summary to the GitHub Actions step summary (GITHUB_STEP_SUMMARY) or prints it if unavailable. Keeps existing subsequent steps intact.
