Function useTransport

useTransport(): {
    send: (event: TransportEvent) => void;
    status: TransportStatus;
    type: TransportType;
}
Subscribe to the current transport connection status and expose a stable send callback.

Returns {
    send: (event: TransportEvent) => void;
    status: TransportStatus;
    type: TransportType;
}
- status — current TransportStatus ('idle' when not connected).
- type — active TransportType (null when not connected).
- send — stable callback to dispatch a TransportEvent to the room.
Remarks
Wraps the module-level transportManager singleton so React components don't need to import it directly. Status updates trigger re-renders; send is memoised and never changes identity.
Example
```
function BuzzerButton() {
  const { status, send } = useTransport()
  return (
    <button
      disabled={status !== 'connected'}
      onClick={() => send({ type: 'BUZZ', playerId, playerName, timestamp: Date.now() })}
    >
      Buzz!
    </button>
  )
}
```
