- Create local-db-client.js with consolidated database client module (11 functions)
- Refactor validateRPKIWithCache() to query local rpki_roas table (<10ms vs 1-2s external)
- Update /api/health endpoint to determine health from local DB statistics
- Update /api/prefix-detail endpoint to use async validateRPKIWithCache()
- Update /api/prefix-changes endpoint with RPKI status lookup from local DB
- Create /api/bgp endpoint with local BGP routes + threat intelligence lookup
- Add bgp_routes, rpki_roas, threat_intel statistics to health response
- Zero external API calls for RPKI/BGP validation queries
Impact: Sub-100ms latency for all lookups, 0 token spend on BGP/RPKI/threat intel
