billantony/call-WhiskeySockets ? reverse-engineered prompt

Build me a small JavaScript module for WhatsApp calls that works with Baileys and lets me start and end real time calls from code.

I want it to connect to an existing Baileys WhatsApp session, handle microphone audio, play incoming audio in the browser, and support more than one WhatsApp account at the same time. It should expose simple methods like initialize, startCall, endCall, and processAudioChunk, and it should be easy to plug into an Express app with a few endpoints for starting calls and sending audio. Please include a working example file and a simple browser demo so I can see how the audio stream is handled.

Make it friendly for someone who just wants to install it and get calls working quickly. If you need to check the latest Baileys or browser audio docs, look them up online first.
