Function createEchoBridge

createEchoBridge(
options: EchoBridgeOptions,
): { install(bus: BaseBus): void; teardown(): void }
createEchoBridge — wire Laravel Echo / Reverb realtime channels to the bus.

Protocol-aware over the generic WS bridge: subscribes public / private / presence channels and routes each broadcast to bus.emit() (or a command via onBroadcast). Presence membership (here / joining / leaving) is emitted too. Receive-only by design — outbound commands still go through the HTTP bridge. Pass your own Echo instance; the bridge never imports laravel-echo, so non-Laravel consumers don't pay for it.
Parameters
- options: EchoBridgeOptions
Returns { install(bus: BaseBus): void; teardown(): void }
Example
```
import Echo from 'laravel-echo';
const echo = new Echo({ broadcaster: 'reverb', ... });
const realtime = createEchoBridge({
  echo,
  channels: [
    { name: 'orders', type: 'private', events: ['OrderShipped', 'OrderCancelled'] },
    { name: 'lobby',  type: 'presence', events: ['MessagePosted'] },
  ],
});
realtime.install(bus);   // OrderShipped → bus.emit('OrderShipped', payload)
// on teardown:
realtime.teardown();
```
