/**
 * @claude-flow/memory - V3 Unified Memory System
 *
 * Provides a unified memory interface backed by AgentDB with HNSW indexing
 * for 150x-12,500x faster vector search compared to brute-force approaches.
 *
 * @module @claude-flow/memory
 *
 * @example
 * ```typescript
 * import { UnifiedMemoryService, query, QueryTemplates } from '@claude-flow/memory';
 *
 * // Initialize the memory service
 * const memory = new UnifiedMemoryService({
 *   dimensions: 1536,
 *   cacheEnabled: true,
 *   embeddingGenerator: async (text) => embeddings.embed(text),
 * });
 *
 * await memory.initialize();
 *
 * // Store entries
 * await memory.store({
 *   key: 'auth-patterns',
 *   content: 'OAuth 2.0 implementation patterns for secure authentication',
 *   tags: ['auth', 'security', 'patterns'],
 * });
 *
 * // Semantic search
 * const results = await memory.semanticSearch('user authentication best practices', 5);
 *
 * // Query with fluent builder
 * const entries = await memory.query(
 *   query()
 *     .semantic('security vulnerabilities')
 *     .inNamespace('security')
 *     .withTags(['critical'])
 *     .threshold(0.8)
 *     .limit(10)
 *     .build()
