mindesbunister 7ff78ee0bd feat: Hybrid RPC fallback system (Alchemy → Helius) ...

- Automatic fallback after 2 consecutive rate limits
- Primary: Alchemy (300M CU/month, stable for normal ops)
- Fallback: Helius (10 req/sec, backup for startup bursts)
- Reduced startup validation: 6h window, 5 trades (was 24h, 20 trades)
- Multi-position safety check (prevents order cancellation conflicts)
- Rate limit-aware retry logic with exponential backoff

Implementation:
- lib/drift/client.ts: Added fallbackConnection, switchToFallbackRpc()
- .env: SOLANA_FALLBACK_RPC_URL configuration
- lib/startup/init-position-manager.ts: Reduced validation scope
- lib/trading/position-manager.ts: Multi-position order protection

Tested: System switched to fallback on startup, Position Manager active
Result: 1 active trade being monitored after automatic RPC switch
