Add an auto-install wizard accessible from the ConnectionStatus dialog
when Claude Code CLI is not detected (Electron only).
- Electron main: install orchestrator with IPC handlers for check/start/cancel
- Preload: expose install API via contextBridge
- InstallWizard: multi-step dialog with real-time log streaming
- ConnectionStatus: add "Install Automatically" button when disconnected
