Rip out Ollama: direct_route only, no LLM layer

Pete moves to a remote host without Ollama access. Every source must
declare a direct_route channel; the classifier, explainer, semantic
dedup, !explain summaries, feed_hint, and the recent_headlines /
classification_log tables are gone. Deterministic dedup (canonical URL,
headline_norm, per-channel cooldown) remains.
