feat(editor): NPC scatter tool, adjacent tile creation, multi-tile prep

Browse source 
- Scatter tool: place N creatures in a radius around cursor position
  with random rotation and uniform disk distribution
- File > Add Adjacent Tile: creates and exports a blank tile N/S/E/W
  of current (foundation for multi-tile zone editing)
- Scatter UI: count slider (1-30), radius slider (10-200)
- Scatter places all copies with same stats/behavior as template
