critical: Fix Bug #87 - Add 3-tier SL verification with circuit breaker

CRITICAL FIX: Prevents silent stop-loss placement failures that caused $1,000+ losses Created lib/safety/sl-verification.ts (334 lines): 60s → 90s delays - Queries Drift protocol directly via user.getOpenOrders() - Filters SL orders: marketIndex + reduceOnly + TRIGGER_MARKET/LIMIT - Circuit breaker: haltTrading() blocks new trades on verification failure - Emergency shutdown: Force-closes position after 3 failed attempts - Event-driven architecture: Triggered once post-open (not polling) - Reduces Drift API calls by ~95% vs continuous polling Integrated in app/api/trading/execute/route.ts: - Line 54: Import shouldAcceptNewTrade for pre-execution check - Lines 215-221: Circuit breaker validates trading allowed (HTTP 503 if halted) - Lines 583-592: Triggers SL verification post-open (fire-and-forget) Root Cause - Bug #76: Silent SL placement failure Database Evidence: Trade cmj8abpjo00w8o407m3fndmx0 - tp1OrderTx: 'DsRv7E8vtAS4dKFmoQoTZMdiLTUju9cfmr9DPCgquP3V...' ✅ EXISTS - tp2OrderTx: '3cmYgGE828hZAhpepShXmpxqCTACFvXijqEjEzoed5PG...' ✅ EXISTS - slOrderTx: NULL ❌ - softStopOrderTx: NULL ❌ - hardStopOrderTx: NULL ❌ User Report: 'RISK MANAGEMENT WAS REMOVED WHEN PRICE WENT TO SL!!!!! POSITION STILL OPEN' Reality: SL orders never placed from start (not cancelled later) Solution Philosophy: 'better safe than sorry' - user's words Safety: Query on-chain state directly, don't trust internal success flags Deployed: 2025-12-16 13:50:18 UTC Docker Image: SHA256:80fd45004e71fa490fc4f472b252ecb25db91c6d90948de1516646b12a00446f Container: trading-bot-v4 restarted successfully

+/**
+ * SL Verification System - Post-Open Safety Checks
+ * 
+ * Purpose: Verify stop loss orders are actually placed on-chain after position opens
+ * Prevents Bug #76 (Silent SL Placement Failure) from leaving positions unprotected
+ * 
+ * Architecture: Event-driven verification with exponential backoff (30s, 60s, 90s)
+ * - Queries Drift on-chain state, not just database
+ * - 3 verification attempts with increasing delays
+ * - If all fail: Halt trading + close position immediately
+ * 
+ * Rate Limit Impact: ~3-9 queries per position (vs 360/hour with interval-based)
+ * 
+ * Created: Dec 16, 2025 (Bug #76 root cause + user mandate "better safe than sorry")
