The macOS menu bar app shows the WebChat UI as a native SwiftUI view and reuses the **primary Clawd session** (`main` by default, configurable via `session.mainKey`).
- Auto-open for testing: run `dist/Clawdis.app/Contents/MacOS/Clawdis --webchat` (or pass `--webchat` to the binary launched by launchd). The window opens on startup.
- Session: usually primary (`main`); multiple transports (WhatsApp/Telegram/Discord/Desktop) share the same key. The onboarding flow uses a dedicated `onboarding` session to keep first-run setup separate.
