/**
 * writeFacts — persist extracted facts to the memory store.
 *
 * Reads from scope:  `newFacts`, `identity`
 * Writes to store:   MemoryEntry<Fact> per fact via `store.putMany`
 *
 * Ids are `fact:${key}` (set by `extractFacts` via `factId`). Because
 * `putMany` overwrites on id collision, a second turn writing the same
 * key REPLACES the prior entry. This is the contract for facts — they
 * dedup by key, unlike beats and messages which are append-only.
