Add a DJGPP CMake toolchain file and DOS compatibility layer (err.h, fnmatch, getprogname/setprogname) so UC2 builds as a native DOS executable via cross-compilation from Linux. The toolchain works around a baked-in /usr/include in the DJGPP GCC binary by using -I instead of -isystem to ensure DJGPP headers take precedence. Add GitHub Actions CI workflow that builds and smoke-tests on both ubuntu-latest and macos-latest.
