Subject: [PATCH] feat(editor): one-click Generate Complete Zone pipeline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- File > Generate Complete Zone: runs the full procedural pipeline
  in one click: noise → smooth (3 passes) → recalc normals →
  height-based auto-paint (sand/grass/rock/snow) → slope-based
  cliff paint (rock on steep faces)
- Creates a fully textured, natural-looking zone from flat terrain
- Removed stale quickGenerate checkbox from New Terrain dialog
