.DESCRIPTION
    Scans F:\CI\Logs\ (or a custom path) for invoke-ci.jsonl files and
    prints a compact table with job ID, status, total elapsed time, and the
    last error message (if any).

    Each row corresponds to one completed (or failed) CI job.
    Use -JobId to inspect a single job in detail.

.PARAMETER LogDir
    Base directory containing per-job log subdirectories.
    Default: F:\CI\Logs

.PARAMETER Last
    Show only the N most recent jobs (sorted by job-start timestamp).
    Default: 20

.PARAMETER JobId
    When specified, shows a detailed phase-by-phase breakdown for that job.

.PARAMETER Failed
    When specified, filters to failed jobs only.

.EXAMPLE
    # Show last 20 jobs
    .\Get-CIJobSummary.ps1

.EXAMPLE
    # Show last 5 failed jobs
    .\Get-CIJobSummary.ps1 -Last 5 -Failed

.EXAMPLE
    # Detailed breakdown for a specific job
    .\Get-CIJobSummary.ps1 -JobId 'run-12345'
