Add a horizontal strip of discovered tether devices to the window: the store
polls engine.nearby() every 2s while connected and renders each as a chip with
its friendly name + platform icon. Tapping a device calls pair() — sets room to
that device's room and reconnects, so you join it without typing a room id.
Devices already in your room show "in your room" (disabled).
Verified live on macOS: two named LAN devices appear as "tap to join" chips
once the app has Local Network permission.
