Fix JUnit XML int parsing and force Node.js 24 for download-artifact

- Cast count attributes to int() in JUnit XML generation (CFML returns
  floats for numeric values, causing ValueError in publish action)
- Set FORCE_JAVASCRIPT_ACTIONS_TO_NODE24 on publish-results and
  test-matrix-summary jobs (download-artifact@v6 still ships Node 20)
