Crate bot_engine 

Bot Engine: order manager, inventory ledger, event routing, and polling.

This crate contains the runtime that:

• Manages order state (in-memory source of truth)
• Tracks inventory/balances with reservations
• Routes events to strategies
• Handles rate limiting and backoff
• Manages exchange health state machine
• Polling loop for fills and quotes (native only)
• Trade syncing to upstream API for PnL tracking (native only)
