FastAPI service replacing the 77-node n8n pipeline. Implements full
discovery pipeline: 29 rotating SearXNG queries, nomic-embed-text
scoring against Last.fm taste centroid, Mistral-nemo prefilter and
curator with provenance validation, SQLite dedup, writes to
metal-picks.json for the existing FGS dashboard.
Runs as systemd service on port 8766 (fgs-agent.home via Caddy).
n8n reduced to a 2-node schedule trigger → HTTP POST.
