.SYNOPSIS
    Cleanup script to manually remove the Autopilot Monitor agent.

.DESCRIPTION
    This script removes all traces of the Autopilot Monitor agent:
    - Stops and removes the Scheduled Task
    - Deletes C:\ProgramData\AutopilotMonitor folder

    Normally the agent self-destructs after enrollment completion.
    Use this script only for manual cleanup or troubleshooting.

.EXAMPLE
    .\Uninstall-AutopilotMonitor.ps1

.NOTES
    - Requires Administrator privileges
    - Safe to run multiple times
    - No Registry cleanup needed (agent doesn't use Registry)
