rightkit-tauri-shell 0.4.0

//! Test and bench binaries that link Tauri need the Common Controls v6 side-by-side manifest on Windows.
//!
//! Tauri's window stack (tao, wry, muda) imports `TaskDialogIndirect` from comctl32, which exists only
//! in version 6. An application gets the manifest from `tauri-build`; a Cargo test binary has none, so
//! the loader binds comctl32 v5 and the process dies before `main` with `STATUS_ENTRYPOINT_NOT_FOUND`
//! (0xC0000139). On an interactive session the loader also shows a modal error dialog, which hangs
//! an unattended build host. Embedding the dependency in the test binaries fixes the cause. The
//! build host should additionally run tests with `SEM_FAILCRITICALERRORS` set (`SetErrorMode`), which
//! children inherit and which turns any other loader failure into a plain exit code instead of a dialog.
