Fix Baileys Integration

My Node.js project relies on the Baileys library for a WhatsApp API integration, and I’m currently stuck on some stubborn integration issues. The code compiles, but the connection either drops unexpectedly or fails to initialise altogether, so messages never reach WhatsApp. I need a developer who already knows the quirks of Baileys—hand-shakes, QR sessions, event handling, reconnection loops, everything—and can dive straight into my repo, pinpoint the breaking points, and patch them.

Here’s what I expect once you’re in:
• Audit the existing setup, spot any mis-configured options, race conditions, or outdated Baileys calls.
• Implement the fixes directly in the source, keeping the overall project structure intact.
• Explain the root cause in plain language so I can avoid the same pitfall later.
• Show me a short test run—connect, send a sample message, receive the correct acknowledgment—to prove the integration is solid.

The codebase is small and well-documented, lives on a private GitHub repo, and uses TypeScript, dotenv for config, and simple logging through pino. If additional npm packages or a specific Baileys version are needed, just flag them and I’ll handle the installs. Push your working branch, I’ll pull it down, run it locally, and once the above test passes, we’re done.
