Add macOS menu bar app with chat and settings

- Restructure project into three targets:
  - AppleIntelligenceCore: Shared gRPC service code
  - AppleIntelligenceServer: CLI server
  - AppleIntelligenceApp: Menu bar app

- Menu bar app features:
  - Toggle server on/off from menu bar
  - Chat window with streaming AI responses
  - Settings: host, port, API key, auto-start, launch at login
  - Proper window focus handling for menu bar apps

- Add build scripts for distribution:
  - build-app.sh: Creates signed .app bundle
  - create-dmg.sh: Creates distributable DMG
