// scripts/test-strategy-nudge.mjs — ECO-41 verification.
//
// Asserts the website-strategy nudge flow:
//   1. After Module 1 completes, bot sends module1_complete_strategy_url
//      (the URL message), NOT the old dossier_pending one
//   2. WhatsApp dossier flow does NOT auto-fire (gated behind env flag)
//   3. runStrategyNudges fires strategy_nudge_daily once per >22h, capped at 7
//   4. markStrategyCompleted via admin endpoint flips state + sends ack
//   5. pollStrategyOnDisk detects a manual write and flips state
//
