Function encodeConnect

encodeConnect(opts: ConnectOptions): Uint8Array
Encodes a CONNECT packet for MQTT v3.1.1.

Writes the fixed protocol name MQTT, protocol level 4, the connect-flags byte (clean session, and the username/password presence bits), the keep-alive, and the payload (client id, then any username and password). Lean on TLS for confidentiality; the credentials travel in cleartext inside this packet.
Parameters
- opts: ConnectOptions
  The client id, keep-alive, clean-session flag, and optional credentials.
Returns Uint8Array
The complete CONNECT packet bytes.
Throws
If a field exceeds the wire size limits.

Since
1.0.0
Example
```
import { encodeConnect } from 'edgeport/mqtt';

const bytes = encodeConnect({ clientId: 'edge-1', keepAliveSeconds: 60, cleanSession: true });
```
