// TestLiveReminderFire performs ONE real reminder fire against a live Telegram
// chat and the live Google Sheet, exercising the full scheduler send path:
// Syncer.Sync -> Store.Snapshot -> reminderText -> mention -> BotSendFunc.
//
// It is a manual smoke test, skipped unless DYZUR_LIVE_FIRE=1, and needs the same
// env the binary uses: BOT_TOKEN, GROUP_CHAT_ID, GOOGLE_CREDENTIALS_FILE, GOOGLE_SHEETS_ID
// (and ROTA_CACHE_PATH for the cache file).
//
// WARNING — this MUTATES the sheet. fire() announces the current week and, when
// that week is empty, auto-assigns two people and WRITES their names into the
// rota. Point GROUP_CHAT_ID at a SANDBOX chat AND GOOGLE_SHEETS_ID at a COPY of
// the sheet — otherwise this pings real members and edits the production rota.
