/**
 * AgentDB Performance Benchmarks
 *
 * Measures and verifies performance claims:
 * - "150x faster" vector search (baseline vs HNSW)
 * - "84% faster" QUIC sync (baseline vs AgentDB)
 * - "10-100x faster" neural training (baseline vs AgentDB RL)
 * - "4-32x memory reduction" (quantization effects)
 *
 * These benchmarks provide PROOF for marketing claims.
