feat: setup project infrastructure

- Create folder structure (server, client, install)
- Add server package.json with LiveKit SDK, Express, Opus
- Add client package.json with React, Vite, livekit-client
- Add macOS installation script with LiveKit binary download
- Add basic YAML config (1 group, 2 channels, audio quality settings)
- Add .gitignore for dependencies and binaries
