# Description:
# This script automates the deployment of a Home Assistant virtual machine (VM) in VirtualBox.
# It checks the latest Home Assistant OS release version from GitHub, compares it to the locally
# installed version, and creates a new VM if the latest version is not already installed.
#
# Key Features:
# - Dynamically fetches the latest Home Assistant OS release version using GitHub API.
# - Compares it with the currently installed local version.
# - Automatically downloads, extracts, and configures the latest version as a VirtualBox VM.
# - Ensures that VM configuration parameters (e.g., memory, CPUs) are pre-set.
# - Supports user confirmation before proceeding with download and deployment.
