543b185f7e fix: address code quality issues from review 
- Make ConnectReceived thread-safe with Volatile.Read/Write (accessed from auth timeout task and command pipeline)
- Include authTimeoutTask in Task.WhenAny to propagate exceptions
- Clear nonce after authentication with CryptographicOperations.ZeroMemory
- Avoid closure allocation on publish permission cache hot path (method group)
- Update AuthTimeout default to 2s to match Go server
