A user's plezy.exe 2.13.0 crashed on every launch with an access violation
in C:\WINDOWS\SYSTEM32\MSVCP140.dll 14.29.30139.0 (VS 2019-era redist). CI
builds with the current VS 2022 toolset, and since 17.10 std::mutex uses a
constexpr layout that an older msvcp140.dll misreads, so the app dies inside
the DLL before the first frame. Nothing shipped the runtime: the bundle,
installer, portable archive, and MSIX all relied on whatever redist the
machine happened to have.
Install the MSVC runtime DLLs next to plezy.exe via
InstallRequiredSystemLibraries; app-local copies precede System32 in the DLL
search order, so the bundled version always wins. One install rule covers the
installer, portable 7z, and MSIX, which all package the Release directory.
The Windows bundle verification in build.yml now requires msvcp140.dll and
vcruntime140.dll so a silently missing redist dir fails CI instead of
shipping.
