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.

+# inside the build-image (see ../../build-image/Dockerfile, built/pushed
+# via ../../build-image.sh and ../../upload-image.sh), which bundles
+# every dependency engine/ needs to compile - no network access needed
+# at job runtime. Since the job's container already *is* the build-image
+# (QUESTSHOCK_BUILD_IMAGE=1), `make package`'s `engine` prerequisite
+# compiles directly instead of trying to docker-run it again, which
+# wouldn't work here (no nested docker).
