Builder uses golang:1.23-bookworm (matches runner-base:go-ci).
Runtime is debian:bookworm-slim with ffmpeg (server spec §3) plus a
non-root minstrel user. Release workflow builds from this Dockerfile.
Establishes the embed.FS and migrations/ layout up front. Migrate()
returns ErrNotConfigured intentionally — the real goose runner lands in
M2 alongside Postgres work, avoiding a toolchain bump to Go 1.24/1.25
through goose's transitive modernc.org/libc dependency chain.
Parses --config / SMARTMUSIC_CONFIG, loads YAML config with env overlay,
initializes slog, starts the chi HTTP server, and shuts down cleanly on
SIGINT/SIGTERM.
Initial module at git.fabledsword.com/bvandeusen/minstrel pinned to go
1.23.0 to match the runner-base:go-ci image. Dependencies kept minimal
(chi router, yaml.v3) so CI's first run is fast and contained.
