feat: initialize proxy pool on first remote player update

Calls InitializeProxyPool() when first remote player is processed.
This discovers all pre-placed proxies in the current cell and logs:
- Number of proxies found
- Max concurrent players supported
- Warning if no proxies found

The proxy pool is now ready for use when assigning proxies to
remote players. Since we only use pre-placed proxies with proper
AI, animations should now work smoothly.
