File-Level Changes

Change	Details	Files
Guard the disconnect handler to avoid reconnecting on the very first connection attempt before a QR code is generated.	Compute an isInitialConnection flag based on the absence of wuid and zero QR code generation count. Short‑circuit the disconnect handler when isInitialConnection is true, logging a message and skipping reconnection. Preserve existing behavior for shouldReconnect logic and subsequent reconnection handling when not in the initial connection state.	src/api/integrations/channel/whatsapp/whatsapp.baileys.service.ts

<issue_to_address>
**issue (bug_risk):** Guard against `this.instance.qrcode` being undefined before accessing `.count`.

If `qrcode` isn’t initialized when disconnect runs, this will throw at runtime. Consider a defensive access pattern (e.g. `this.instance.qrcode?.count ?? 0`) so this remains safe during unusual initialization or disconnect sequences.
