Sets up a basic server instance, handles player connections, and spawns entities into the game world.

```typescript
import { MavonServer, MavonClient, Entity } from '@mavonengine/core'

// Server-side game world
const server = new MavonServer()

server.onPlayerJoin((player) => {
  const entity = new Entity({ position: [0, 1, 0] })
  server.world.add(entity)
  server.sync(player, entity)
})

server.start(3000)
