Removed the AI Chat widget in v2.0.6

[amnweb]

The AI Chat widget is gone in v2.0.6 preview, and it won't be coming back in the upcoming stable release either (fully removed, not just deprecated).

If you have an ai_chat block in your config, delete it. If you don't, you'll get an "unknown widget type" error on startup and the widget won't build.

Why? It was a fun experiment, and honestly some people did really great work on it - attachments, streaming, Copilot support, all of that was impressive. But it never really felt like it belonged in a status bar. It pulled in the openai and github-copilot-sdk SDKs, plus a ton of chat UI and streaming code to maintain. And those deps changed so often that every update seemed to break something. I got tired of chasing it, and I'd rather spend that time on the bar itself.

If you were using it and actually want it back - the code is still in git history (v2.0.5 and earlier) and it's MIT licensed, so it could live on as a separate project if someone wants to pick it up.
