name: Build MSI Check

# Lightweight PR check that validates msi/RDPWInst.wxs compiles cleanly.
# We stub the binary inputs (DLL/EXE) with placeholder files so WiX can
# validate the package structure without needing a full C++ / C# build.
# For the real release build with actual binaries, see build-and-release.yml.
