feat(editor): add --add-creature CLI for headless creature placement

Browse source 
Appends a single creature spawn to a zone's creatures.json. First
real authoring tool that doesn't need the GUI placement system —
useful for batch-populating zones via shell script:

  for npc in goblin spider wolf; do
    wowee_editor --add-creature "$zone" "$npc" 100 200 50
  done

Args: <zoneDir> <name> <x> <y> <z> [displayId] [level]
- displayId 0 → SQL exporter substitutes 11707 (generic humanoid)
- level defaults to 1
- Coordinates are render-space (renderX=wowY, renderY=wowX)

Loads any existing creatures.json first then appends, so multiple
invocations build up the file. The standard NPC spawner caps
(50k creatures) protect against runaway scripts.
