- npm start / watch:telegram: add --env-file=env so TELEGRAM_* and HTTPS_PROXY from nv reach process.env
- watcher: import CONFIG.candleWindowMinutes from src/config.js so the per-window latch stays in sync with the bot
- watcher: replace prevSide/cooldown latch with lastSentWindowId keyed on floor(ts/WINDOW_MS); one alert per window, NO_TRADE rows no longer reset state
