feat: wire live decision loop and enable paper trading
Phase 2 of the autonomous trading engine: - Replace start()/stop() stubs with real async implementations - Decision loop: polls recommendations from PostgreSQL, deduplicates via Redis, evaluates through the full pipeline, submits orders to stonks:queue:broker_orders - Stop-loss monitor: fetches prices from Polygon API, checks crossings, submits immediate sell orders, safety sell after 15 min without data - Performance loop: computes metrics every 5 min during market hours, persists daily snapshots at market close - Risk tier scheduler: evaluates daily at 16:00 ET, persists tier changes - Rebalance scheduler: evaluates Monday 09:45 ET, respects circuit breaker - Notification dispatch: SNS + Gmail with rate limiting and retry - Backtest replay: fetches historical data, simulates decisions, persists - Real asyncpg/redis connections in FastAPI lifespan (graceful degradation) - Migration 019: enable paper trading with conservative tier, 5 cap - Added max_open_positions to TradingConfig with env var loading - Phase 2 tasks added to autonomous-trading-engine spec
