Module prerequisites 

Windows desktop runtime prerequisites (WebView2 + VC++ redistributable).

WebView2: prefer a Fixed Version runtime shipped next to the executable (WebView2Runtime/ or WebView2/). If absent, fall back to the system Evergreen runtime (registry). Sets WEBVIEW2_BROWSER_EXECUTABLE_FOLDER when a bundled runtime is found.

VC++ 2015–2022 x64: not redistributable inside QualiaDB — user installs Microsoft’s installer; we detect via registry and re-check after launch.
