Do not let diagnostic logging block staging.
If this metadata request times out, returns an HTTP error, or lacks info, Python exits before portable-msvc.py runs. A diagnostic request can therefore fail the MSVC prefetch step independently of the installer. Give the request a timeout and catch its failures so staging still proceeds.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Check version directories before reusing an MSVC stage.
If an interrupted SDK extraction creates Windows Kits/10/bin but no version directory, this check skips restaging. The later next(...glob("*")) call then fails, and subsequent prefetch runs keep failing until the stage is removed manually. Check for the required version directories before treating the stage as complete.
