The .msi shortcuts already carry the icon, but the bare goblin.exe had none, so Explorer/taskbar showed the generic exe icon. build.rs now embeds wix/Product.ico (the yellow Goblin icon) as the exe's application icon resource. Gated to Windows hosts: winresource is a `cfg(windows)` build-dependency and the embed fn is `#[cfg(windows)]` (with a no-op stub otherwise), so Linux/macOS/ Android builds don't compile or run it — other releases are untouched. The embed is best-effort (warns, never fails the build) in case rc.exe is unavailable.
