State transitions are driven by `WCallResponse` messages from the WebRTC layer. Each transition typically triggers a corresponding API command (e.g., `apiSendCallInvitation`, `apiSendCallOffer`).
**Reconnection**: `Connected` -> `Reconnecting` -> `Connected` or `Ended`. When a connected call loses its WebRTC connection, `call.js` reports `"reconnecting"` connection state instead of ending the call. The app sets `CallState.Reconnecting` and plays the connecting sound; this state is not sent to the core with `apiCallStatus`, so the call item duration is not affected, and `connectedAt` is kept. The party that sent the initial offer (callee) restarts ICE every 10 seconds until reconnected: the restart offer and the answer are sent as `WCallResponse.Ice` / `WCallCommand.Ice` with `session`, via `apiSendCallExtraInfo` (`x.call.extra` with `rtcSession`). If the connection is not restored in 30 seconds, `call.js` reports `"disconnected"` and ends the call.
