Shows a small message box with version metadata + build info. Used as a fastest possible end-user smoke check after install: double-click drover.exe in a portable bundle (or run 'drover gui' from cmd) and see "OK — the binary launched and the Windows API is reachable" with the right version on screen. No network calls, no admin needed. Implementation: cgo-free, uses only golang.org/x/sys/windows (already pulled in by the updater package). gui_other.go is a stub so the package still compiles on Linux for the CI smoke build. Locally verified: built with -X main.Version=test-local, ran 'drover.exe gui' on Windows 11, message box appeared with correct version/commit/Go runtime info.
