.SYNOPSIS
    Smoke test for the CI pipeline. Validates the full lifecycle end-to-end
    using a trivial no-op build.

.DESCRIPTION
    Invokes Invoke-CIJob.ps1 with a minimal build command (write a marker file)
    and checks that the pipeline completes successfully:
      - Invoke-CIJob.ps1 exits 0
      - Artifact directory is created: F:\CI\Artifacts\<JobId>\
      - invoke-ci.jsonl contains a job-success event

    This script can be run directly on the CI host without act_runner.
    It is also invoked by gitea/workflows/self-test.yml via the composite action.

.PARAMETER GuestOS
    Guest OS template to use. Windows (default) or Linux.

.PARAMETER TemplatePath
    Override the VMX template path. Defaults to the standard template for
    the chosen GuestOS.

.PARAMETER SnapshotName
    Snapshot to clone from. Default: BaseClean (Windows) or BaseClean-Linux (Linux).

.PARAMETER JobId
    Job ID for this test run. Default: smoke-<timestamp>.

.PARAMETER VmrunPath
    Path to vmrun.exe. Default: C:\Program Files (x86)\VMware\VMware Workstation\vmrun.exe

.EXAMPLE
    # Test Windows template
    .\Test-Smoke.ps1

.EXAMPLE
    # Test Linux template
    .\Test-Smoke.ps1 -GuestOS Linux
