   2   * Tests for src/cron.js — coverage supplement targeting uncovered HANDLERS code paths
   3   *
   4   * Covers:
   5   * 1. backupDatabase — with temp backup dir (lines 497-768): full backup body
   6   * 2. analyzePerformance — empty tables (missing ANALYZE stats path, lines 951-979)
   7   * 3. checkKeywords — with seeded data (lines 171-201)
   8   * 4. purgeSiteStatusHistory — with overflow data (lines 1066-1109)
   9   * 5. checkRateLimits — with missing env vars (lines 1038-1064)
  10   * 6. unifiedAutofix — error path (lines 1298-1312): script doesn't exist
  11   * 7. logTaskComplete — items_processed field (lines 1569-1570)
  12   * 8. logTaskComplete — metrics.processed field (line 1568)
  13   * 9. executeCommand — via command-type job via runCron
  14   * 10. analyzePerformance — full structure returned correctly
  15   *
  16   * NOTE: requires --experimental-test-module-mocks flag
