🚦 Smart Entity Control
Automatic per-chunk limits for:

Golems
How it works:
- On spawn attempt, plugin checks chunk limit
- If exceeded → spawn denied
- Player-caused spawns are not affected
- All limits customizable
🔍 Heavy Chunk Detection
Automatic detection of laggy areas:
Scan all loaded chunks
Count entities
Send warnings
Show exact coordinates
Show top-5 heaviest chunks
Example:
Heavy chunks:
🏗️ Chunk (123, 456) → 245 entities
🏗️ Chunk (-89, 234) → 189 entities
🏗️ Chunk (567, -123) → 156 entities
