install_docker.ps1

<#
  Morphik Core - Docker installer for Windows PowerShell.

  This mirrors install_docker.sh (macOS/Linux) and sets up a Docker-based deployment.

  Usage (PowerShell):
    Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
    ./install_docker.ps1

  Requirements:
    - Docker Desktop running (Compose V2 included)
    - Internet connectivity to pull the image or fetch config files
