Smoke test: health check + NL-to-Cypher. Use after starting the API to confirm backend and Ask the graph work.

Neo4j 5.x constraints and indexes for the multi-agent hunter system. Defines:

• Node labels from all hunter specs (01–10): Supply chain (MaliciousPackage, LegitimatePackage, SuspiciousPackage), AI threat (LeakedAPIKey, JailbreakTechnique, WeaponizedAIModel, AIMalware, LLMServiceAbuse), Insider (InsiderRecruitment, DataExfiltrationOffer, DisgruntledEmployee), Synthetic ID (DeepfakeService, VoiceCloningService, KYCBypassTool), PhysicalSecThreat, ExploitMarketListing, SocialCorrelation, GitHubSecretLeak, APTAttribution, ThreatScore, plus core/IOC types (IOC, WalletAddress, Identity, Indicator, ThreatActor, DAO, Account, File, DivergenceAlert, SuspectedFaP).
• Relationship types documented in the script header (e.g. TYPOSQUATS, DISTRIBUTES, SELLS, SAME_OPERATOR) with range indexes on key relationship properties (e.g. TYPOSQUATS.distance, TYPOSQUATS.confidence, SAME_OPERATOR.confidence) for query performance.
• Idempotent use of IF NOT EXISTS for migrations and re-runs.
• Design alignment with NEW ADDITIONS/Research/Deep Dive into Cypher Script.md: specific relationship types for index-free adjacency, explicit constraint/index names, composite index property order for common filters, optional Enterprise-only constraints in comments.
