- RiskManager halts + flattens on max daily loss / drawdown, caps position
size and trades per day; adds a manual kill switch (POST /api/bot/kill).
- Telegram and webhook notifications on trades, errors and halts.
- Optional API bearer token on /api, injected server-side by the frontend
nginx so the browser never sees it.
- Kraken and Coinbase market data (public); Coinbase live broker. Live on an
unsupported exchange now errors instead of silently falling back to paper.
- Strategy presets backed by the StrategyConfig table (CRUD API + UI).
- Idempotent additive-column migration so existing SQLite databases upgrade in
place (fixes the new strategy_configs.name column).
