Solo Event Spawner

This is based on player location and will spawn a US vs FIA skirmish/encounter event THAT HAS A LIVING TENSION SYSTEM.

The system spawns US and FIA patrols and vehicles around the player at safe, visible distances on flat ground away from water. It tracks player kills to increase spawn frequency, starting slow and ramping up with sustained combat. Active groups are limited by type and faction to avoid overcrowding. Old or distant units are removed automatically. Everything runs smoothly with no setup required.
