v0.11.467+11467-macos

## OMI Desktop v0.11.467

### What's New
- Faster, cheaper assistant responses via Anthropic prompt caching of the system+tools prefix and conversation history
- Added an experimental Realtime Voice Hub (Settings → Floating Bar): the realtime model handles your whole voice turn — listening, deciding, and speaking — for noticeably faster replies
- Redesigned the floating bar voice indicator with smooth, distinct idle, listening, thinking, and speaking states so you always know whether the assistant is working or done
- Voice (push-to-talk) conversations now appear in your chat history
- Fixed older chat messages failing to load in long chats
