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.

+#!/bin/bash
+# fix-genre.sh — quickly override the GENRE tag for every track by an artist.
+#
+# Use when spotify-genre.py picks something wrong (e.g. it tagged Yasuha as
+# "Asian Music" when "Anime; Soundtrack" is what you actually want), or when
+# you want to set a genre on an artist Spotify doesn't have data for.
+#
+# The new value is written to file tags AND beets's DB. The next nightly
+# spotify-genre run will leave these alone (they already match the whitelist
+# format), unless you pass --force.
+#
+# Usage:
+#   fix-genre.sh "<artist>" "<Genre1; Genre2; ...>"        # apply
+#   fix-genre.sh --dry "<artist>" "<Genre1; ...>"          # preview only
+#
+# Examples:
+#   sudo fix-genre.sh "Yasuha" "Anime; Soundtrack"
+#   sudo fix-genre.sh "Aphex Twin" "IDM; Electronic; Ambient"
+#   sudo fix-genre.sh --dry "Mac DeMarco" "Indie; Indie Rock"
