/**
 * Integration tests — POST /api/memory/reindex
 * Tests: no force → {started:true, pending:N}, force=true marks all needs_reindex, 401 unauth.
 *
 * NOTE: runReindexBatch and getReindexPending are named ESM exports that cannot be mocked via
 * mock.method. We test with the real DB — the route returns immediately with pending count
 * and dispatches the batch in background (setImmediate). Since the batch runs asynchronously
 * and may fail silently (no embedding configured), we just verify the immediate response shape.
