/**
 * Summarize Step — ported from KB sleep/steps/summarize.ts.
 *
 * AI-powered summary generation:
 * - Finds memories with no summary, very short summary, or raw JSON blobs
 * - Generates tier-appropriate summaries (rich for hot, compressed for archive)
 * - Limited to maxSummariesPerRun to control LLM costs
 *
 * Adapter note: KB reads files from disk and uses getSleepDb for the
 * maintenance_queue. Arcana uses memory.content directly (already stored)
 * and deps.structured.updateMemory.
