The bug: selecting a state filter in AI Search mode did nothing
because HNSW vector search has no concept of SQL WHERE clauses.
Results came back from any state.

The fix: when ANY filter is set (state, role, or reliability > 0.5),
the search automatically switches to hybrid mode which runs the SQL
filter first, then AI-ranks within the filtered set. Users don't
need to know about modes — filters just work.
