'exit 0' left C:\CI\build\dist non-existent -> packaging skipped -> Get-BuildArtifacts
could not find artifacts.zip -> all 4 jobs FAIL at artifact collection phase.
New default: 'if not exist dist mkdir dist & echo burnin_ok > dist\marker.txt'
This creates dist\marker.txt relative to C:\CI\build (GuestWorkDir), so the
packaging step finds it, creates artifacts.zip, and Get-BuildArtifacts succeeds.
Also updated docblock: clarify command runs via cmd /c; replace Start-Sleep example
(PS cmdlet, does not work via WinRM cmd) with ping delay equivalent.
scripts/Test-CapacityBurnIn.ps1 (new): N-way parallel burn-in harness using Start-Job
to launch N concurrent Invoke-CIJob.ps1 child processes for R rounds. After each round
asserts: all VMs destroyed, all jobs got distinct IPs, vm-start.lock gone, ip-leases
empty, wall time recorded. Params: -RepoUrl (mandatory), -IPList = @() (optional,
auto-detects via VMware Tools when empty), -GiteaCredentialTarget = 'GiteaPAT',
-Parallelism = 4, -Rounds = 3, -RoundTimeoutMinutes = 60, plus all Invoke-CIJob params.
scripts/Start-BurnInTest.ps1 (new): lab wrapper with all default params hardcoded
(template F:\CI\Templates\WinBuild2025, credentials BuildVMGuest/GiteaPAT, etc.)
for daily use. Exposes -Rounds, -Parallelism, -BuildCommand, -RoundTimeoutMinutes.
