/**
 * Graph storage adapters for LearnGraph
 *
 * Provides a unified interface for storing skill graphs with multiple
 * backend options:
 * - **MemoryStorage**: In-memory storage for testing
 * - **LevelGraphStorage**: Browser/local storage using triples
 * - **Neo4jStorage**: Production graph database
 *
 * @example
 * ```typescript
 * import { MemoryStorage, Neo4jStorage, LevelGraphStorage } from 'learngraph/storage';
 *
 * // For testing
 * const testStorage = new MemoryStorage();
 * await testStorage.connect({ backend: 'memory' });
 *
 * // For browser/local development
 * const localStorage = new LevelGraphStorage();
 * await localStorage.connect({ backend: 'levelgraph', path: './my-graph' });
 *
 * // For production
 * const prodStorage = new Neo4jStorage();
 * await prodStorage.connect({
 *   backend: 'neo4j',
 *   uri: 'bolt://localhost:7687',
 *   username: 'neo4j',
 *   password: 'password',
 * });
 *
 * // Same API for all!
 * const skill = await storage.createSkill({ ... });
 * const prereqs = await storage.getPrerequisitesOf(skill.id);
 * ```
