Moves all ~30 pipeline scripts, configs, and the vendored sldl binary into this repo (source /opt/sldl left untouched). Removes all docker exec/docker compose dependencies now that beets and sldl run in-process/as a subprocess of this container instead of via soulbeet/on-demand sldl containers. Replaces hardcoded host paths, Navidrome credentials, and Spotify credential sourcing with env-var-driven paths and shared credential loaders. Adds Dockerfile, entrypoint.sh, requirements.txt, docker-compose.snippet.yml, and the initial app DB schema.
