Vendor the Shockolate engine and build it via a Docker image with every

dependency (SDL2, SDL2_mixer, fluidsynth-lite, a MIDI soundfont) prebuilt, so compiling the engine needs no network access - just the image and the engine source. Add res/assets/extract_assets.sh to pull the game's data files out of a purchased GOG installer, and a Makefile that assembles a runnable dist/ from the two. Also add `make package`, which builds a redistributable tarball that omits the proprietary game assets (shipping res/GET_ASSETS.txt instead) plus license information for both the MIT tooling and the GPLv3 engine, and a Gitea Actions workflow that builds and publishes it to dl.ladkau.de on every push.
