Chrome Enterprise MSI — Fast Auto-Arch Installer (PowerShell)

Downloads and silently installs Google Chrome Enterprise MSI with the correct architecture
(x64 on 64-bit OS, x86 on 32-bit OS).
Fast, resilient download pipeline: curl.exe → BITS → Invoke-WebRequest with retries and timeouts.
No version checks (handled elsewhere by design).

Official Google endpoints always deliver the latest available version.
