/**
 * @file storage-roundtrip.test.js — e2e storage integration test.
 *
 * Boots a fake env with:
 *   - MongoKVStore (backed by fake-mongo) for KV path (wordle)
 *   - MongoTradesStore (backed by fake-mongo) for SQL/trades path (trading)
 *   - DUAL_WRITE=1 so DualKVStore is used (CF KV + Mongo both written)
 *
 * Asserts that state written via the store abstractions is visible in BOTH
 * backends — the CF KV fake AND the in-memory Mongo fake.
 *
 * This test intentionally avoids grammY context setup. It exercises the
 * storage layer (the thing being migrated), not the Telegram handler.
