All-Chat Extension Autor: Caesar

All-Chat Extension replaces the native chat on Twitch, YouTube, YouTube Studio, and Kick with a unified overlay that aggregates messages from all connected streaming platforms into a single view.

Features:
- Unified chat view across Twitch, YouTube, Kick, and YouTube Studio
- Real-time WebSocket connection for instant message delivery
- Platform badges showing where each message originated
- Third-party emote support (7TV, BetterTTV, FrankerFaceZ)
- Emote autocomplete with colon-trigger (e.g. :pog)
- Viewer authentication to send messages from any platform
- Custom name colors and gradients
- Auto-detects live streams and replaces native chat automatically

How it works:
When you visit a supported streaming platform, the extension checks if the streamer uses All-Chat (allch.at). If they do, native chat is replaced with the All-Chat overlay showing messages from all their connected platforms in one place.
