Subject: [PATCH] feat(editor): minimap objects/NPCs, NPC duplicate, legend

- Minimap now shows placed objects (yellow dots) and NPCs (red=hostile,
  green=friendly) at their world positions on the height grid
- NPC Duplicate button: copies selected creature with 10-unit offset
  for quick population of similar spawns
- Minimap legend: colored dots showing Object/Hostile/Friendly markers
- All positions correctly mapped from world coords to minimap UV space
