ProxyManager

Each bot runs an independent pollLoop goroutine. Dual-mode per bot:

Proxy mode: forwards raw updates to backend URL
Management mode: processes updates for chat/message tracking

Both can be active simultaneously.

UpdateQueue

In-memory ring buffer (1000 updates per bot) with waiter notification pattern. Multiple consumers can poll simultaneously.

Bot Resolution

API endpoints resolve bots through a fallback chain:

Check registered bots map
Check ProxyManager’s managed bots
