assessed='no' (Not assessed) was truthy, forcing hasEnrichFilter=true and
routing to SQLite even when prescreen_status='none'. But domains that have
never been prescreened don't exist in SQLite at all → 0 results every time.
Rule: if prescreen_status='none', always use DuckDB. Enrichment-only
filters (niche, site_type, country, assessed) are irrelevant for domains
that haven't entered the pipeline and must not override the DuckDB path.
