/**
 * BedrockAgentMemory — read the **auto-generated session-summary memory** of a
 * (legacy) Amazon **Bedrock Agents** agent (peer-dep `@aws-sdk/client-bedrock-agent-runtime`).
 *
 *   import { BedrockAgentMemory } from 'agentfootprint/memory';
 *
 *   const mem = new BedrockAgentMemory({ agentId, agentAliasId, region: 'us-west-2' });
 *   const summaries = await mem.readSummaries(userMemoryId);   // string summaries Bedrock wrote
 *
 * **This is NOT a `MemoryStore`** — and intentionally so. Bedrock Agents *owns the writes*:
 * the agent generates `SESSION_SUMMARY` records itself (`GetAgentMemory` reads them,
 * `DeleteAgentMemory` clears them). There is no "put an arbitrary entry" operation, so wrapping
 * it as a `defineMemory({ store })` would be a "store that can't store." Instead it's a small
 * **reader** you use to *surface* Bedrock's built-in memory — e.g. inject the summaries as a
 * Fact/context block into an agentfootprint agent.
 *
 * For a real read/write agent memory store on AWS, use `AgentCoreStore` (the newer
 * Bedrock **AgentCore** platform) — that's the go-forward path; this targets the prior-gen
 * Bedrock Agents product and exists for teams migrating off it.
 *
 * Role:   Outer ring. Lazy-requires the AWS SDK; zero cost when unused.
