changAI - Update - Voice enabled

[fkalpana]

We just gave ChangAI a voice. 🗣️
Our latest update brings Voice & Speech Settings to ChangAI — now you can interact with your data through conversation, not just typing.

Here's what we shipped:

1. Auto Read Replies — hear ChangAI's responses out loud
2. Amazon Polly integration — crisp, natural TTS powered by AWS (free up to 5M characters/month!)
3. Browser Speech support — zero setup, works everywhere
4. A brand new Settings tab to control it all

It's a small toggle. It's a big experience upgrade.
