ci(windows): load MSVC dev environment before building

rustc resolves link.exe via PATH for the windows-msvc target, but Git for
Windows ships GNU coreutils' link.exe which shadows MSVC's linker, breaking
every build-script link. Add ilammy/msvc-dev-cmd@v1 before the tauri build so
PATH/LIB/INCLUDE point at the real MSVC toolchain (and it fails fast if MSVC
is missing instead of at link time).
