.SYNOPSIS
Automates the setup and connection to a DevContainer environment using either Docker or Podman on Windows.
.DESCRIPTION
This script automates the process of initializing, starting, and connecting to a DevContainer
using either Docker or Podman as the container backend. It must be executed from the root
directory of your project and assumes the script is located in a 'Script' subdirectory.
.PARAMETER Backend
Specifies the container backend to use. Valid values are 'docker' or 'podman'.
.EXAMPLE
.\Script\run_devcontainer_claude_code.ps1 -Backend docker
Uses Docker as the container backend.
.EXAMPLE
.\Script\run_devcontainer_claude_code.ps1 -Backend podman
Uses Podman as the container backend.
