Subject: [PATCH] feat(rag): add database routing to 8 more factual query
 templates

Add databases: ["oxigraph"] to skip vector search for deterministic queries:
- count_institutions_by_type_location (count)
- count_institutions_by_type (aggregation)
- find_institutions_by_founding_date (temporal)
- find_custodians_by_budget_threshold (financial)
- compare_locations (comparative)
- find_by_founding (temporal)
- events_in_period (temporal events)
- institutions_by_founding_decade (temporal aggregation)

Total templates with oxigraph-only routing: 12
