Detailed Description

Main game server plugin for R-Type multiplayer gameplay.

This class implements the complete server-side game logic including:

Entity management (players, enemies, projectiles, powerups)
Collision detection and resolution
Enemy AI and behavior
Wave-based enemy spawning
Player input processing
Score tracking
Game state synchronization
World state broadcasting to clients
Game over detection

The server operates at a fixed tick rate and broadcasts world state to all connected clients. All gameplay logic is server-authoritative to prevent cheating and ensure synchronized gameplay across all clients.
