build / build (push) Successful in 3m5s
issues on vboxsf-mounted checkouts New `make dist-win`/`package-win` targets (folded into `dist`/`package` alongside the renamed `dist-linux`/`package-linux`) cross-compile systemshock.exe via MinGW, using prebuilt SDL2/SDL2_mixer/GLEW/ fluidsynth-lite baked into the build-image - no Windows machine or Wine needed to build it, confirmed working and playable on a real Windows machine. dist-win/ ships DLLs flat alongside the exe plus a new res/run.bat launcher, packaged into a .zip the same way dist/ becomes a .tar.gz. Also fixes three build-image bugs hit while testing on a VirtualBox vboxsf-mounted checkout: build-engine.sh/docker-entrypoint.sh losing their execute bit (chmod +x on restrictive source perms), the container user missing access to /workspace's supplementary vboxsf group, and cp -a failing on symlink/hard-link creation (vboxsf doesn't support either) - now falls back to dereferencing copies when detected. Also adds Docker/zip/etc. prerequisites to the README for both the desktop and Quest builds.
