gitea/burnin-dummy/build.ps1: Fake build script to commit to the burnin-dummy repo. Creates dist\build-info.txt (date, host, pid) after ~30s ping delay. Invoke-RemoteBuild packages dist\ as artifacts.zip. Start-BurnInTest.ps1: Default BuildCommand updated from ping-only delay to build.ps1 invocation. Run with -NoSkipArtifact to exercise the full artifact pipeline.
