Units will only attack enemy zones within 15km

If no zones are in range, they'll stay as defenders or idle
This prevents the "path too long" error that caused the crash
You can adjust MAX_ATTACK_DISTANCE if needed (lower = more stable, higher = longer range attacks)

New Metrics Added:

Tracked Groups - Total number of groups being managed by the plugin (should match or be close to "Total Active Units")
Lua Memory - Current Lua script memory usage in MB
Warnings:
High memory warning if Lua memory > 500MB
High group count warning if > 200 groups
What to watch for:

Lua Memory steadily increasing over time = memory leak (groups not being cleaned up)
Tracked Groups != Total Active Units = dead groups not being removed from tracking table
Group count approaching MAX limits = might hit spawn caps
This will help you identify if memory is building up before it causes a crash. Check the F10 menu → Show System Statistics periodically during long missions to monitor these values.
