.SYNOPSIS Installs the Claude desktop application by downloading and provisioning its MSIX package.

.DESCRIPTION This script performs a secure, non-interactive installation of the Claude application. It handles prerequisite checks (Administrator rights), downloads the latest MSIX file from a predefined URL, verifies if the application is already installed (idempotency check), and provisions the package system-wide using Add-AppxProvisionedPackage.

.NOTES Requires PowerShell execution with Administrator privileges.
