drover.exe is now a GUI subsystem binary:
- Double-click no longer flashes a console window — a clean
smoke-test message box opens immediately.
- When run from cmd / PowerShell, AttachConsole reattaches stdout
and stderr to the parent terminal so '--version', 'check', etc.
still print as expected.
- MB_TOPMOST flag added to MessageBox so the window can't be
obscured by other windows on launch (this was the actual cause
of "I clicked but nothing happened" reports).
Verified locally: built with GOOS=windows GOARCH=amd64 -H=windowsgui;
running drover-gui.exe --version prints to PowerShell, drover-gui.exe
gui shows the message box on top of the active window.

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.
