  2   * Tests for src/cron.js — TASKS handler body coverage
  3   *
  4   * Uses mock.module() to mock external dependencies so handler bodies
  5   * can be called directly without spawning real child processes or API calls.
  6   *
  7   * Covers:
  8   * - Lines 71-81: syncEmailEvents handler
  9   * - Lines 87-97: syncUnsubscribes handler
 10   * - Lines 103-113: pollInboundSMS handler
 11   * - Lines 119-133: pollPurchases handler
 12   * - Lines 39-60: checkAndClearStaleLock (called within handlers)
 13   *
 14   * NOTE: requires --experimental-test-module-mocks flag
