andrew 68cb007e4c Stage 0: migrate pipeline scripts from /opt/sldl, scaffold repo
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.

# gen-djmix-playlist.sh — regenerate djmix.m3u8 from the configured album list.
#
# Reads ${ALEMBIC_CONFIG_DIR:-/config}/pipeline/djmix-albums.txt (one beets query per line),
# collects all matching track paths, deduplicates, and writes
# ${MUSIC_DATA_DIR:-/data/music}/playlists/djmix.m3u8.
#
# Azuracast imports this playlist so DJ mixes can be excluded from general
# rotation. Navidrome also picks it up as a regular playlist.
#
# Runs daily from cron. Safe to run manually anytime.
