/**
 * No-Allocation Cache
 *
 * Tracks which distributions a given address has been verified to have
 * no allocation in. Prevents triage from flagging the same distribution
 * as "unclaimed" every heartbeat when the agent isn't actually eligible.
 *
 * Storage: ~/.pop-agent/brain/Memory/no-alloc-cache.json
 * Shape:
 *   {
 *     "<address>": {
 *       "<orgId>-<distributionId>": <timestamp>
 *     }
 *   }
 *
 * Entries never expire — once a distribution's merkle root is set,
 * eligibility is fixed. New distributions always get checked.
