Detailed Description

Serializes and deserializes game state for network transmission.

Responsibilities:

• Create full game state snapshots
• Generate delta updates (only changed entities)
• Serialize entity components to network format
• Ensure deterministic entity ordering

Network Efficiency:

• Full snapshots sent on connect or major state changes
• Delta updates sent every frame (only changed entities)
• Position/health deltas with compression
