Phase 8 deleted the Python models for these tables; this migration
drops the orphan SQL.
Dropped tables (CASCADE-safe):
conversations, messages, generation_tool_log,
moments + moment_embeddings + moment_people/places/tasks/notes,
pending_curator_actions, push_subscriptions, weather_cache,
rss_item_embeddings (legacy pre-pivot experiment)
Dropped per-user settings: every voice_*, journal_*, briefing_*,
curator_* key, plus default_model, background_model, assistant_name,
auto_consolidate_tasks, chat_retention_days, think_enabled,
rag_default_scope.
Hard cutover — no downgrade. Existing data in these tables is lost;
the spec explicitly accepted this in exchange for a clean schema.
