/**
 * State Management Module
 *
 * Provides conversation persistence and session management.
 * Inspired by LangGraph's checkpointer pattern.
 *
 * @example
 * ```typescript
 * import { FileCheckpointer, JsonSerializer } from '@compilr-dev/agents';
 *
 * // Create checkpointer
 * const checkpointer = new FileCheckpointer('~/.myapp/sessions/');
 *
 * // Use with agent
 * const agent = new Agent({
 *   provider,
 *   checkpointer,
 *   autoCheckpoint: true,
 * });
 *
 * // Or manually checkpoint
 * await agent.run('Hello!');
 * const sessionId = await agent.checkpoint();
 *
 * // Resume later
 * const resumed = await Agent.resume(sessionId, { provider, checkpointer });
 * ```
