Detailed Description

Server-side system that manages enemy wave spawning and level progression.

This ECS system controls the flow of enemy spawns throughout a game session. Features include:

Time-based wave triggering
Multiple enemy types per wave (basic, advanced, boss)
Gradual spawning with configurable intervals
Random spawn position generation
Wave progression tracking
Spawn statistics for debugging

The system maintains internal state for level time and wave progression, and spawns enemies at the right edge of the screen with random Y positions. All spawning is deterministic based on server time to ensure synchronized gameplay across all clients.
