Parent failures inflate headless output

Low Severity

Parse-TestResults collects every test-case with result='Failed', including parent nodes that wrap child cases. The new headless harness prints that list directly, so nested Unity failures can show duplicate or less useful parent entries. report-test-results.ps1 already skips those parents when rendering the same XML.
